Fast electrically switchable large gap quantum spin Hall states in MGeZ
Rajibul Islam, Ghulam Hussain, Rahul Verma +4
Spin-polarized conducting edge currents counterpropagate in quantum spin Hall (QSH) insulators and are protected against disorder-driven localizations by the time-reversal symmetry…
Unprotected edge modes in quantum spin Hall insulator candidate materials
Nguyen Minh Nguyen, Giuseppe Cuono, Rajibul Islam +3
The experiments in quantum spin Hall insulator candidate materials, such as HgTe/CdTe and InAs/GaSb heterostructures, indicate that in addition to the topologically protected helic…
Switchable large-gap quantum spin Hall state in two-dimensional MSiZ materials class
Rajibul Islam, Rahul Verma, Barun Ghosh +4
Quantum spin Hall (QSH) insulators exhibit spin-polarized conducting edge states that are topologically protected from backscattering and offer unique opportunities for addressing…
Tunable spin polarization and electronic structure of bottom-up synthesized MoSiN materials
Rajibul Islam, Barun Ghosh, Carmine Autieri +4
Manipulation of spin-polarized electronic states of two-dimensional (2D) materials under ambient conditions is necessary for developing new quantum devices with small physical dime…
