这种新的电子器件(称Ebird)具有半导体的寿命长和电子管的高功率放大的特点,今年初开始在市场上出售,成为包括RCA在内几个厂商的主要研究课题。该器件的电子源对半导体对阴极是负偏压的,因此射束电子用10千电子伏的能量打到二极管上。这个二极管便处于低于其雪崩阈值的反向偏压。没有电子 This new electronic device, called the Ebird, has been featured in the long life of semiconductors and the high power amplification of electron tubes. It was initially sold on the market earlier this year and has become a major research topic for several vendors, including RCA. The electron source of the device is negatively biased towards the cathode of the semiconductor, so the beam electrons hit the diode with 10 keV of energy. This diode is at a reverse bias below its avalanche threshold. No electronics
