avalanche photodiode

基本解释

The edge pre-breakdown of planar-type avalanche photodiode(APD) is resulted from the intense electric field at the junction bend.
平面型雪崩光电二极管（APD）在结弯曲处具有高的电场，导致在结边缘的提前击穿。
The operating principles, structures and characteristics of avalanche photodiode(APD)and photomultiplier tuber(PMT)are presented.
介绍了雪崩光电二极管（APD）和光电倍增管（PMT）的工作原理、结构及其特性；
The measurement results of the avalanche photodiode (APD) and the photomultiplier tube (PMT) are compared, the similar accuracy was obtained.
同时比较了雪崩二极管和光电倍增管的测量结果，两者的测量精度相当。
