本文报道第一个沟道光电探测器的工作情况。这种仪器能象极高灵敏度的光电容探测器那样工作;用很低的功率(约20微微瓦)就可获得电容的较大变化(约1微微法)。此外,还可以把这种结构用作极低电容(约0.06微微法)低穿通电压的pin光电二极管,这种结构各层的掺杂浓度和探测器面积具有很大的独立性。该器件代表了最近才显露出的电子和空穴雪崩区相隔开的低噪声雪崩光电二极管的最初发展。
This article covers the operation of the first channel photodetector. The instrument works like a very sensitive photoconductive detector; a very large change in capacitance (about 1 picofarad) can be achieved with very low power (about 20 pw). In addition, the structure can also be used as a very low capacitance (about 0.06 pico-method) low pass-voltage pin photodiode structure of this layer doping concentration and detector area has great independence. The device represents the initial development of a low-noise avalanche photodiode that has recently been revealed to separate electrons and hole-avalanche regions.
