Synthesis

Atomically Thin And A Few Nm Thick Transition Metal Compounds

SCMLab research begins at the synthesis level. Our main focus lies compounds of transition metals with group 6a elements. In particular we are interested in understanding the synthesis routes that lead to atomically thin transition metal dichalcogenides and VO2 nanocrystals. In our most recent effort we developed a chemical vapour deposition synthesis chamber that allows real time optical observation and control of the synthesis.

The video shows real time formation of atomically thin WSe₂ crystals. This is a first ever demonstration of monolayer TMDC crystals forming in real time. Taken from our recent pre-print “Real time optical observation and control of atomically thin transition metal dichalcogenide synthesis”.

Optoelectronics

Optoelectronics Of Strongly Correlated Materials

Using scanning photocurrent microscopy method, we investigate optoelectronics of strongly correlated materials. Recently, we started working on low temperature optoelectronics of layered transition metal dichalcogenides.
