Piezo-topological transistor.Schematic of a piezo-topological transistor using DSM thin film as the channel material. a The thin film is initially in the trivial insulating phase, so the transistor is in off state. b By applying strain to the channel region, the thin film is driven to the QSH phase with topological edge channels for conducting current. Hence the transistor is turned on. The topological channels are robust and have low heat dissipation
