Off-resonant light-induced topological phase transition and thermoelectric transport in semi-Dirac materials

Vassilios Vargiamidis, P. Vasilopoulos, Neophytos Neophytou

We show that a semi-Dirac (SD) system with an inversion symmetry breaking mass exhibits a topological phase transition when irradiated with off-resonant light. Using Floquet theory…

Valley-dependent tunneling through electrostatically created quantum dots in heterostructures of graphene with hexagonal boron nitride

A. Belayadi, N. A. Hadadi, P. Vasilopoulos +1

Kelvin probe force microscopy (KPFM) has been employed to probe charge carriers in a graphene/hexagonal boron nitride (hBN) heterostructure [Nano Lett, 21, 5013 (2021)]. We propose…

Valley-controlled transport in graphene/ WSe heterostructures under an off-resonant polarized light

M. Zubair, P. Vasilopoulos, M. Tahir

We investigate the electronic dispersion and transport properties of graphene/WSe heterostructures in the presence of a proximity-induced spin-orbit coupling , sublatt…

Influence of interface-induced valley-Zeeman and spin-orbit couplings\\ on transport in graphene-on-WSe heterostructures

M. Zubair, P. Vasilopoulos, M. Tahir

We investigate the electronic dispersion and transport properties of graphene/WSe heterostructures in the presence of a proximity induced spin-orbit coupling (SOC) using a lo…

Tunable topological phases in monolayer PtHgSe with exchange fields

Vassilios Vargiamidis, P. Vasilopoulos, Neophytos Neophytou

We investigate topological phases of monolayer jacutingaite (PtHgSe) that arise when considering the competing effects of spin-orbit coupling (SOC), magnetic exchange inter…

Berry curvature, orbital magnetization, and Nernst effect in biased bilayer WSe

Vassilios Vargiamidis, P. Vasilopoulos, M. Tahir +1

A valley-contrasting Berry curvature in bilayer transition metal dichalcogenides with spin-orbit coupling can generate valley magnetization when the inversion symmetry is broken, f…
