Abstract

Harvesting ambient electromagnetic energy requires broadband, low-power rectification, which is challenging to achieve with conventional diodes. Now, using the nonlinear Hall effect in thin films of the topological crystalline insulator SnTe, wireless, zero-bias rectification is demonstrated across megahertz to terahertz frequencies and with sensitivity down to ambient power levels.

用非线性霍尔整流器在宽频率上收集能量

收集环境电磁能量需要宽带、低功率整流，这是传统二极管难以实现的。现在，利用拓扑晶体绝缘体SnTe薄膜中的非线性霍尔效应，在兆赫到太赫兹的频率范围内演示了无线零偏整流，灵敏度低至环境功率水平。
