Speaker: Dr. Maxim Trushin
Affiliation: NUS Centre for Advanced 2D Materials, Singapore
Abstract Details: We develop an analytically solvable model able to qualitatively explain non-hydrogenic exciton spectra observed recently in two-dimensional (2D) semiconducting transition-metal dichalcogenides. Our exciton Hamiltonian explicitly includes additional angular momentum associated with the pseudospin degree of freedom unavoidable in 2D semiconducting materials with honeycomb structure. We claim that this is the key ingredient for understanding the non-hydrogenic exciton spectra that was missing so far.About the speaker Maxim Trushin is a Senior Research Fellow at the Center for Advanced 2D Materials, National University of Singapore. He obtained his PhD from the University of Hamburg in 2005. From 2006 to 2012 he worked as academic employee at the University of Regensburg (Ratisbonne) and at the University of Konstanz (Constance) from 2012 to 2017. In the period between 2009 and 2010, he was a research fellow at the University of Texas at Austin under a German Research Foundation fellowship. Maxim’s expertise and research interests lie in the theoretical understanding of the electronic properties of semiconductor nanostructures, spintronics, and the optical and transport properties of two-dimensional materials and hybrid structures."Click HERE for directions
