Robust electro-mechanical actuation in hydrogenated Xenes leading to reversible topological transition

Sujith Nedungattil Subrahmanian, Nabendu Mondal, Joydeep Bhattacharjee

We report from first principles, the possibility of reversible onset of topological insulator(TI) phase in heavier hydrogenated Xenes (Xane), namely, germanane and stanane, exclusi…
