A Microwave-Heat-Thermoelectric Cascade Platform for Dynamic Therapy Based on Schottky-Engineered Bismuth Telluride Nanosheets

Abstract

Recombination of electron and hole in thermoelectric materials leads to unsatifactory ROS generation. We synthesize a bismuth telluride nanosheet-based Schottky heterojunction, which enables directional electron transfer to suppress electron-hole recombination and enhances the ROS generation. When exposed to microwave, material can generate a large amount of ROS for tumor suppression.
