I started to set up my lab at Nanjing University in 2013. The current research interest in our group is topological materials. We tried to grow thinfilms or monolayered topological insulators with molecular beam epitaxy and look at the surface with scanning tunneling microscopy. Meanwhile,
we also tune the films properties by tuning the growth kinetics.

Daegu

Monolayer 1Tʼ-WTe² is a candidate of quantum spin Hall material, and has been attracting great attentions. However, to precisely determine theband structure near Fermi energy is out of the resolution scale of ARPES. STM quasiparticle interference (QPI) provides a high resolution way tomap out the constant energy contour. In a recent paper, we grew monolayer 1Tʼ-WTe² on bilayer SiC substrate and systematically imaged the QPI.
We undoubtedly figured out the bulk band is semimetal like with no full SOC gap, and we also found a Coulomb gap opened at Fermi energy due
to the electron-electron interactions.

We are a research group at the Leiden Institute of Physics. We work
hard to explore and understand quantum materials, including strange
metals, high-temperature superconductors, and quantum criticalelectron matter. Recently, we have focused on cuprate and iron-based
high-temperature superconductors. We always want to combine novel
science and instrumental development. For example, we modified
our UNISOKU USM1500 to include shot-noise capabilities with a lowtemperature amplifier developed in our group [1].
This allowed us to make new discoveries on cuprate superconductors [2]and we believe that there is much more to come.
We are now working with UNISOKU to make this amplifier more widely
available. In parallel, we are working on Josephson tunneling, and —together with our Leiden theory colleagues — on experimental testsof the AdS/CFT correspondence in strange metals. You can find more
information on allanlab.org.

Recent result
S. Liu, M. Wolf, and T. Kumagai, Phys. Rev. Lett. 121, 226802 (2018).
We have developed a low-temperature scanning probe microscope equipped withoriginal in-situ optics for local optical excitation and spectroscopy. Using this new
instrument, we observed plasmon-assisted resonant electron tunneling from a silveror gold tip to field emission resonances (FERs) of a Ag(111) surface induced bycontinuous-wave laser excitation of a scanning tunneling microscope (STM) junction
at visible wavelengths (Fig. 1). As a hallmark of the plasmon-assisted resonant tunneling, a downshift of the first peak in the FER spectra by a fixedamount equal to the incident photon energy is observed (Fig. 2). The STM-induced luminescence measurement for the silver and gold tip
reveals the clear correlation between the laser-induced change in the FER spectra and the plasmonic properties of the junction. These results
clarify a novel resonant electron transfer mechanism in a plasmonic nanocavity.

Yin et al. (Hasan group, Princeton University) reported unprecedented giant
and anisotropic tuning of electronic states in a kagome ferromagnet Fe³Sn²
using a combination of superconducting vector magnets and low temperature
STM. The geometry of kagome lattices (lattices consisting of corner sharing
triangles) is known to exhibit intriguing phenomena associated with frustrated,correlated and topological electronic states. This situation becomes more entangled
in the presence of strong spin-orbit coupling as expected in Fe³Sn² and has
remained unexplored. They discovered that quasiparticle interference patterns
unambiguously change depending on the direction of external magnetic fields.
This result indicates that vector magnetization is capable of altering the
many-body electronic states, which cannot be explained by conventional Zeeman
physics and thus leads to the realization of a correlated magnetic topological phase,and also offers a new way of exploring emergent phenomena in topological quantum
materials.

Ko et al. (An-Ping Li group, Oak Ridge National Laboratory) performed in-situ
transport measurements with a four-probe STM to investigate the intrinsic
surface state of a bulk-insulating topological insulator Bi²Te²Se. The bulk andsurface conductivity was separately obtained by measuring four-probe resistancewith variable probe spacing and temperature. The spin polarization of carriers
was also successfully detected by utilizing a ferromagnetic probe. The observed
transport properties of topological surface states showed a carrier mobility of
61000 cm²/Vs, the highest reported so far, and current-induced spin polarizationof 72 %, indicating nearly scattering-free transport as expected from the theory.
These results suggest that the combination of multiprobe technique and STM
is a powerful tool to study topological transport phenomena and could be further
extended to advanced measurements such as nanoscale conductance mapping.

Matetskiy et al. (Saranin group, Russian Academy of Sciences) investigatedtransport and magnetotransport properties of the two-dimensional (2D) Au-Tl
compound on Si(111) surface at low temperatures down to 2 K using the fourprobe (4P) STM equipped with a superconducting magnet (up to 8 T).
Reducing the dimensionality of the system is known to be accompanied by the
emergence of various exotic electronic properties, and the in-situ measurement
combining STM and 4P techniques could play a crucial role to study such low
dimensional phenomena. In this letter, the authors discovered that the atomiclayers-thick Au-Tl surface forms nearly free 2D electron gas system and a weak
antilocalization due to strong spin-orbit coupling (SOC) is realized. Since there
are many other possible atomic-layer metal films on silicon possessing different
strength of SOC and spin textures, this study opens a wide range of opportunities
to study low dimensional physics at the atomic-scale limit.

Wang et al. (Gao group, Chinese Academy of Sciences) performed low temperature
STM measurements (T = 0.55 K) on the iron based superconductor FeTe0.55Se0.45(Tc = 14.5 K), a candidate material to realize topological superconductivity.
They observed a sharp zero bias peak in a vortex core that does not split whenmoving away from the core, which is one of characteristic features of Majorana
bound states (MBSs). In addition, the evolution of the zero bias peak as a functionof magnetic field, temperature, and tunneling barrier are comprehensively
investigated and can be reasonably explained in terms of MBS rather thanconventional quasiparticle bound states. Based on these results, they claim
these are clear experimental evidence for MBS in this iron superconductor
and offer possibilities of realizing and manipulating MBS at relatively hightemperatures.

Du et al. (Hai-Hu Wen group, Nanjing University) performed quasiparticle
interference (QPI) measurements around a non-magnetic impurity in a
LiOH-intercalated iron-based superconductor FeSe to investigate whether
the superconducting order parameter changes its sign even without hole pockets.
By considering the phase message of the Fourier transformed QPI at positive
and negative energies between the two gap values, they discovered a clear
signature of the sign change of the order parameter in this material. Since theabsence of hole pockets are common in other Fe-based superconductors suchas intercalated and monolayer FeSe-based systems that exhibit superconductivity
at high temperatures of the order of 40K, this result suggests unifying
understandings of pairing mechanism of Fe-based superconductors.

Chang et al. (Xue group, Tsinghua University) and co-researchers (Parkin group,
Max-Planck Institute) performed variable temperature STM to study the structure
and polarization of a few layer SnTe films over a wide range of temperature.
The enhancement of the ferroelectric transition temperature in 2 atomic layer(AL) SnTe films (Tc~270 K, significantly higher than ~100 K in bulk) was previously
found by this group but the underlying mechanism remained unclear. In thispaper, they discovered the formation of γ-SnTe, which does not exist in bulk
SnTe, is responsible for the enhanced Tc, and the films thicker than 4 AL exhibit
even higher Tc over 400 K. These results provide possibilities of atomically-thin
γ-SnTe films for developing novel polarization-based devices and will initiate
further studies on related two-dimensional ferroelectric materials.

Singlet fission (SF), the ultrafast splitting process of a singlet exciton into two
triplet excitons, has been extensively studied for improving the solar energy
conversion properties (e.g., photovoltaics). In this Letter, Sakai et al. (Hasobe
group, Keio University) synthesized pentacene dimers bridged by a phenylene
at ortho and meta positions, and investigated intramolecular orientation-dependent
multiexciton dynamics using transient absorption (TA) and time-resolved electron
spin resonance. In particular, they succeeded in observing seamless TA signals
from femtosecond to millisecond by using the RIPT method in addition to classicaltechniques, and discovered a significant intramolecular orientation-dependent
SF. The rate constants and quantum yields associated with these multiexciton
dynamics in the pentacene dimers are quantitatively evaluated. The manifestationof the orientation-dependent multiexciton dynamics revealed in this study
provides a new perspective for construction of future optoelectronic and energy
conversion devices.
