- Previous story We introduce a new method for thermal conductivity measurements in nanosheets and nanowires
Strongly Correlated Electron Systems
Electronic correlations, namely electron-electron interactions and electron-lattice interactions lead to exotic phenomena in solid state mater. In our lab our focus is on various aspects of strongly correlated materials. Our research begins from investigation of high quality novel materials synthesis and spans investigation of low temperature electronics and optoelectronics of novel devices.
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 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.
