摘要
本文给出了一种新型热离子光电探测器的结构、特性和理论。这种多数载流子器件,在基本结构上异于普通的p-i-n光电两极管,雪崩两极管及光电三极管,而又区别于其它多子器件:①存在着一个大的中央p+n-结区域,它在功能上类似空穴存储库。③在pn两极管的周围处有一个特殊形状的n++p+n-框架结构。普通光电两极管在633nm的绝对灵敏度为0.35A/W,新器件为1.36A/W。
The construction,characteristics and theory of a new type of thermionic photodetector are described.It is a maiority-carrier device,which differs from conventional p-i-n photodiodes,avalanche photodiodes and photo transistors in basic structure.The main differences between this detetor and other majority-carrier devices are:①There is a large central p+ n- juncture area,whose function is similar to a hole storehouse.②In perphery of pn diode,there is a special ring frame n++ p+ n- sandwich structure.The absolute responsivrty of the new device is 1.36A/W ,while that of the ordinary diode is 0.35A/W.
