The isolation of single-atomic layer graphene has led to a surge of interest in other layered crystals with strong in-plane bonds and weak, van der Waals-like, interlayer coupling. Here we research new properties of two-dimensional chalcogenides (sulfides, selenides, and tellurides) such as MoS2, MoSe2, WSe2, WS2, NbSe2, gallium and indium chalcogenides and others from the huge family of these synthesized and natural materials. In their bulk form chalcogenides may vary from insulators to semiconductors, from metals to superconductors, and exhibit topological insulator properties. We obtain 2D films by mechanical exfoliation from layered van-der-Waals-bonded bulk crystals. The properties of 2D films may differ from the bulk quite dramatically. For example, some indirect band-gap semiconductors turn to direct band-gap ones and become optically active. Our recent effort is on development of hybrid photonic devices comprising these 2D films and artificially built van der Waals heterostructures consisting of atomically thin layers of various materials.
Mirror design and calculated electric field distribution in an open-access microcavity used for experiments with 2D films and heterostructures. The 2D structures are placed on the bottom dielectric mirror. The top mirror has a concave shape and can be positioned at a precise vertical displacement from the bottom mirror.
The group is led by Prof Sasha Tartakovskii, who so far graduated 8 PhD students (+2 more in 2017). In 2016 the group reached its highest number so far of 5 PhD students, Robert Schofield, Oleksandr Skrypka, Thomas Lyons, Alessandro Catanzaro, and Luca Sortino, and 4 postdocs, Tillmann Godde, Scott Dufferwiel, Evgeny Alexeev, and Stefan Schwarz. In 2017, the group size will fluctuate from 7 to 9 people, and will have 5 PhD students and 2 postdocs by the end of the year, with people with origin in the UK, Italy, Russia, Ukraine and Bulgaria.
Our expertise is in photonics and magneto-optics of nano-structured semiconductors. The group occupies dedicated three high-spec optical laboratories (including a state-of-the-art magneto-optics and Raman set-up), and shares access to several other state-of-the-art optics laboratories of Prof M Skolnick’s group. Sample and device fabrication is usually carried out at the National III-V Semiconductor Facility in Sheffield, where we have a dedicated set-up to produce atomically thin flakes and heterostructures. Additionally, we have installed an optical microscopy set-up in one of our labs, where more sample fabrication can be done.
Equipment has just been moved in the new lab. End of May 2016.
Scott is working on a set-up combining a vector magnet and a scanning microcavity in our new lab. June 2016.

We also continue our close collaboration with a leading theorist in the field of 2D materials Prof V Falko (the Director of the National Graphene Institute in Manchester from October 2015). Other important collaborations include: polariton physics theory group of G Malpuech (Clermont-Ferrand); specialist in tunable optical microcavities J Smith (Oxford); 2D materials synthesis group of Hyeon Suk Shin (UNIST, Korea); ultra-fast optical spectroscopy group of M Bayer (Dortmund); quantum optics and ultra-fast spectroscopy group of R Bratschitsch (Munster); plasmonics group of J Baumberg (Cambridge); dielectric coating specialist Helia Photonics (Livingston); low-temperature positioning specialist Attocube Systems (Munich); and the leading supplier of layered materials HQ Graphene (Groningen).
