Abstract
PURPOSE: To measure a coefficient of ionization by carrier collision by means of an amount of photo current produced when a light ray with a special wave length is cast on a semiconductor photodiode.
CONSTITUTION: A bias power source 26 is applied between both electrodes 23 and 24 through an ammeter 25, while a reverse voltage is applied to a PN junction J to form a depletion layer that stretches toward a semiconductor layer Q1. A light ray L1 with a wave length of λ1 that is absorbed within only a semiconductor layer Q2, is cast from Q2 side to obtain photo current in the semiconductor layer Q2 due to an electro-positive hole pair. Then another light ray L2 with a wave length of λ2 that is absorbed within only a semiconductor layer Q3 is cast to obtain photo current in the semiconductor layer Q3due to the electro-positive hole pair; thus evaluating a coefficient of ionization by carrier collision.
