摘要

基于选择性生长金刚石薄膜的金刚石肖特基二极管的 I-V 特性在室温至 473 K 范围内具有温度依赖性。在 298-473 K 范围内，I-V 曲线显示出明显的温度依赖性。电压灵敏度分为两个范围：298 K-373 K 和 373 K-473 K。

High sensitive diamond Schottky diode temperature sensor based on selective grown diamond film

The temperature dependence I-V characteristics of the diamond Schottky diode based on selective grown diamond film has been characterized in a range from room temperature up to 473 K. The selective growth of diamond between tungsten mask can contain some acceptor impurities without intentionally doping. In the range 298–473 K, the I-V curves show an obvious temperature dependency. The voltage sensitivity is segmented into two ranges: 298 K–373 K and 373 K–473 K. The maximum sensitivities are 104 mV/K in the range 298 K–373 K and 18 mV/K in the range 373 K–473 K. Repeated measurement exhibits a good agreement with the first time’s results, indicating that the barrier between tungsten and selective grown diamond is thermally stable.
