title: Replication Data for: Localized Traps Limited Recombination in Lead Bromide Perovskites

description: Traps exert an omnipotent influence over the performance of halide perovskite optoelectronic devices. A clear understanding of the origin and nature of the traps in halide perovskites is the key to controlling them and realizing optimal devices. Herein, the role of localized traps on the optical properties of lead bromide perovskite films is investigated. In the low-temperature orthorhombic phase of CH3NH3PbBr3 perovskite, band-edge carrier dynamics exhibit a powerlaw decay due to the presence of structural-disorder-induced localized traps, which has a depth of ≈40 meV. The continuous distribution of these localized traps gives rise to a broad sub-band-gap emission that becomes more prominent in thicker films with a larger trap density. The presence of this emission only from the hybrid organic–inorganic perovskites points to the vital role of organic dipoles in localized trap states formation. This study explicates the nature of these localized traps as well as their nontrivial role in carrier recombination kinetics, which is of fundamental importance in perovskites optoelectronics

title: Replication Data for: Hot Carriers in Halide Perovskites: How Hot Truly?

description: Abstract: Slow hot carrier cooling in halide perovskites holds the key to the development of hot carrier (HC) perovskite solar cells. For accurate modeling and pragmatic design of HC materials and devices, it is essential that HC temperatures are reliably determined. A common approach involves fitting the high-energy tail of the main photobleaching peak in a transient absorption spectrum with a Maxwell−Boltzmann distribution. However, this approach is problematic because of complications from the overlap of several photophysical phenomena and a lack of consensus in the community on the fitting procedures. Herein, we propose a simple approach that circumvents these challenges. Through tracking the broadband spectral evolution and accounting for bandgap renormalization and spectral line width broadening effects, our method extracts not only accurate and consistent carrier temperatures but also ther important parameters such as the quasi-Fermi levels, bandgap renormalization constant, etc. Establishing a reliable method for the carrier temperature determination is a step forward in the study of HCs for next-generation perovskite optoelectronics.

title: Replication Data for: Topological sensor on a silicon chip

description: An ultrasensitive photonic sensor is vital for sensing matter with absolute specificity. High specificity terahertz photonic sensors are essential for many fields, including medical research, clinical diagnosis, security inspection and probing molecular vibrations in all forms of matter. Widespread photonic sensing technology detects small frequency shifts due to the targeted specimen, thus requiring ultra-high quality (Q) factor resonance. However, the existing terahertz waveguide resonating structures are prone to defects, possess limited Q-factor, and lack the feature of chip-scale CMOS integration. Here, inspired by the topologically protected edge state of light, we demonstrate a silicon valley photonic crystal based ultrasensitive, robust on-chip terahertz topological insulator sensor that consists of a topological waveguide critically coupled to a topological cavity with an ultra-high quality (Q) factor of Q=0.14 ×10^6. Topologically protected cavity resonance exhibit strong resilience against disorder and multiple sharp bends. Leveraging on the extremely narrow linewidth (2.3 MHz) of topological cavity resonance, the terahertz sensor shows a record-high Figure of Merit (FoM) of 4000 [RIU.mm]^(-1). In addition to the spectral shift, the intensity modulation of cavity resonance offers an additional sensor metric through active tuning of critical coupling in the waveguide-cavity system. We envision that the ultra-high Q photonic terahertz topological sensor could have chip-scale biomedical applications such as differentiation between normal and cancerous tissues by monitoring the water content

title: Related Data for: Immobilizing Polyiodides with Expanded Zn2+ Channels for High-Rate Practical Zinc-Iodine Battery

description: Aqueous zinc-iodine battery (AZIB) has the advantage of low cost and high specific capacity but suffer from the soluble polyiodides shuttling and sluggish redox kinetics. Herein, these two limitations are addressed by employing a cathode additive (zirconium hydrogen phosphate, denoted as EI-ZrP) which provides dual functions: an agent for polyiodide confinement, and abundant channels for zinc ion transport. An enlarged crystalline interlayer (from typical 7.5 to 18.3 Å) of the EI-ZrP significantly enhances the ionic conductivity and simultaneously immobilizes polyiodides, leading to an accelerated conversion process. AZIB with EI-ZrP in the iodine cathode exhibits a high capacity retention over 10,000 cycles (with a 0.02‰ decay rate per cycle). Quasi-solid-state Zn-I2 pouch cell has been constructed using hydrogel-paper as separator and EI-ZrP additive, which delivers a high areal capacity under repeated bending. As a proof-of-concept demonstration, the paper battery is integrated to power a wireless flexible pressure sensor system (WFPSS). This strategy may shed light on the rational design of conversion-type cathode materials for both energy storage and flexible portable electronics.

title: Transparent Bamboo with High Radiative Cooling Targeting Energy Savings

description: We have fabricated a bamboo-derived composite with enhanced radiative cooling via a simple solution-based process. The long-wavelength infrared emissivity (εLWIR) for one side is as low as 0.3, to prevent the heat exchange, and the εLWIR of the other side is near unity (0.95), to promote the radiative cooling. The energy saving simulations have been performed in Singapore, suggesting up to 89% energy savings enhancement, when compared with commercial low-E glass.

title: Gun and cash images

description: The dataset contains two datasets, which record 200/600 images. 'GunCash80X80NO200.mat' contains one type of gun and cash '3gun80X80No600.mat' contains three types of gun and cash The data format is matlab mat file, which can be loaded and displayed through the m file "load_GunCash_plot.m". All the images are recorded as 80x80 images, but each image is recorded as a 6400x1 vector. After load the file into matlab, you will find the file "alldata", which is 6402xN and the sample number N equals 200 or 600. Note that the last two rows of "alldata" are the labels of the images. The 6401 row is the label(1/-1) to indicate the existence of a gun, The 6402 row is the label(1/-1) to indicate the existence of a cash note. We use a webcam to record images, which may depict a gun and/or cash (dollar notes). The presence or absence of a gun is the public hypothesis, and the presence or absence of cash is the private hypothesis. The gun and the cash are randomly translated and rotated in each 80x80 grayscale image. The target is to detect the public hypothesis and make the private hypothesis cannot be detected.

title: Replication Data for: Electrically Pumped Topological Laser with Valley Edge Modes

description: Quantum cascade lasers (QCLs) are compact electrically-pumped light sources in the technologically important mid-infrared and terahertz (THz) region of the electromagnetic spectrum. Recently, the concept of topology has migrated from condensed matter physics into photonics, giving rise to a new type of lasing utilising topologically-protected photonic modes that can efficiently bypass corners and defects. Previous demonstrations of topological lasers have required an external laser source for optical pumping, and operated in the conventional optical frequency regime. Here, we report on the first demonstration of an electrically-pumped THz QCL based on topologically-protected valley edge states. Unlike previous topological lasers that relied on large-scale features to impart topological protection, we employ a compact valley photonic crystal design analogous to two-dimensional (2D) gapped valleytronic materials. Lasing with regularly-spaced emission peaks occurs in a sharp-cornered triangular cavity, even with the introduction of perturbations, due to the existence of topologically-protected valley edge states that circulate around the cavity without experiencing localisation. The properties of the topological lasing modes are probed by adding different outcouplers to the topological cavity. This is the first laser based on valley edge states and opens the door to practical use of topological protection in electrically-driven laser sources.

title: Replication Data for: Spotlight on Hot Carriers in Halide Perovskite Luminescence

description: Harnessing hot carriers’ (HC) excess energy is an attractive approach to surpass the Shockley-Queisser limit. Halide perovskites possess desirable slow HC cooling properties for developing next-generation solar cells. Their HC cooling properties on the ultrafast timescale are well-reported using a myriad of techniques. However, there remains a significant gap between the manifestations of such ultrafast phenomena into the steady state, which is crucial towards translation into real-world efficiency enhancements. Here, we illuminate the connection between these two realms in their steady-state photoluminescence spectra with a unified model that retrieves essential HC metrics like carrier temperature and thermalization coefficient under non-equilibrium conditions. Our findings reveal that perovskites’ thermalization coefficients are an order of magnitude lower than incumbent absorbers. Importantly, our direct approach deepens our understanding of HC contributions to efficiency enhancements and enables wider accessibility to the HC research community, which will help accelerate the development of perovskite HC solar cells.

title: Replication Data for: White Electroluminescence from Perovskite–Organic Heterojunction

description: Despite extensive reports on red and green perovskite-based LEDs (PeLEDs), development of white PeLEDs remains limited by the low photoluminescence quantum yield of white-emitting perovskites and the undesired energy-transfer (ET) process occurring in multidomain Ruddlesden–Popper perovskites. While ET is beneficial for achieving efficient monochromatic emissions, the broadband spectrum required for white electroluminescence makes this phenomenon undesirable. Processing-induced physical separation of emitters has been proposed as an effective way to curb ET. Here, it is shown that by adopting a bilayered emitter configuration, achieved through a facile antisolvent-assisted spin-coating process, an increase in spatial separation between the blue perovskite and red emitting organic species employed can be realized. This, in turn, has allowed for effective reduction of ET efficiency, leading to a record efficiency of 1.3%, the highest achieved to date from a perovskite-based white electroluminescent device.

title: Replication Data for: Observation of a topological nodal surface and its surface-state arcs in an artificial acoustic crystal

description: Three-dimensional (3D) gapless topological phases can be classified by the dimensionality of the band degeneracies, including zero-dimensional (0D) nodal points, one-dimensional (1D) nodal lines, and two-dimensional (2D) nodal surfaces. Both nodal points and nodal lines have been realized recently in photonics and acoustics. However, a nodal surface has never been observed in any classical-wave system. Here, we report on the experimental observation of a twofold symmetry-enforced nodal surface in a 3D chiral acoustic crystal. In particular, the demonstrated nodal surface carries a topological charge of 2, constituting the first realization of a higher-dimensional topologically-charged band degeneracy. Using direct acoustic field measurements, we observe the projected nodal surface and its Fermi-arc-like surface states and demonstrate topologically-induced robustness of the surface states against disorders. This discovery of a higher-dimensional topologically-charged band degeneracy paves the way toward further explorations of the physics and applications of new topological semimetal phases.

title: Replication Data for: Halide Perovskite Nanocrystals for Multiphoton Applications

description: Halide perovskite nanocrystals (NCs) are a unique class of NCs with novel properties distinct from traditional semiconductor NCs. These exceptional properties of defect tolerance, large absorption coefficients, high brightness, and narrow emission linewidths stem from their atypical band structure. Their facile synthesis and broad colour tunability have garnered widespread interests for applications in light emitting devices and lasers. One fledging niche area is the field of multiphoton excited emission where their giant nonlinear optical action cross-sections are highly favorable for imaging applications. This Frontier article examines the state-of-the-art in perovskite NCs for multiphoton applications from the materials science and physics perspectives that include their synthesis and non-linear optical characterization. In particular, opportunities and challenges for these exceptional perovskite NCs as potential fluorescence labels for multiphoton deep tissue microscopy are highlighted.
