Theory of interaction-induced renormalization of Drude weight and plasmon frequency in chiral multilayer graphene
Xiao Li, Wang-Kong Tse
We develop a theory for the optical conductivity of doped multilayer graphene including the effects of electron-electron interactions. Applying the quantum kinetic formalism, we fo…
Uncovering edge states and electrical inhomogeneity in MoS2 field-effect transistors
Di Wu, Xiao Li, Lan Luan +8
The understanding of various types of disorders in atomically thin transition metal dichalcogenides (TMDs), including dangling bonds at the edges, chalcogen deficiencies in the bul…
Type-II Dirac surface states in topological crystalline insulators
Ching-Kai Chiu, Y. -H. Chan, Xiao Li +2
We study the properties of a family of anti-pervoskite materials, which are topological crystalline insulators with an insulating bulk but a conducting surface. Using ab-initio DFT…
Exciton-polaritons in transition-metal dichalcogenides and their direct excitation via energy transfer
Yuri N. Gartstein, Xiao Li, Chuanwei Zhang
Excitons, composite electron-hole quasiparticles, are known to play an important role in optoelectronic phenomena in many semiconducting materials. Recent experiments and theory in…
