摘要
谐振隧穿二极管(RTD)具有高频、低功耗、负阻、双稳态、自锁等优点,在超高速数字电路领域具有非常好的应用前景。加之InP材料固有的优越特性,使得InP基谐振隧穿器件成为目前研究的重点。研究并试制了InP基RTD实验样品,对其直流特性进行了测试分析,器件的最大电流峰谷比(PVCR)达到了17.8。
With high device frequency, low power dissipation, negative impedance, bistable and self- locking, resonant tunneling diode (RTD) has a promising application prospect in the ultra high speed digital circuits. Because of the inherent advantages InP-based resonant tunneling devices attract great attention in recent years. InP-based RTD was fabricated, its DC characteristics were investigated, and results show that the maximum peak-to-valley current ratio (PVCR) is 17.8 at room temperature.
