Molybdenum and tungsten based transition metal dichalcogenides(TMDCs) with polymorphs in the hexagonal and distorted octahedral phases ate a class of layered material with fascinating electronic properties.H-TMDCs host massive Dirac fermions and have become a materia system of choice for realizing valleytronics. bulk and monolayer T'-TMDCs are predicted to possess topologically nontrivial electronic bands.
Dr. Jun Yan is an Assistant Professor of Physics at the University of Massachusetts Amherst. He received his Bachelor's degree at Nanjing University in2003, and his PhD at Columbia University in 2009. Afer working as postdoc researcher at the University of Maryland college Park for three years, he joined the physics faculty at UMass Amherst. Dr. Yan's main research focus is on two dimensional electronic systems. He studied electrons confined in GaAs quantum wells in the fractional quantum Hall regime, pioneered electron-phonon interaction studies as well as the bolometric and thermoelectric THz detection of graphene.mor recently his research interest has expanded to the novel properties of transition metal dichalcogenides.
