PULSED LIGHT-INDUCED TRANSIENT BEHAVIOR AT n-InP ELECTRODE IN Fe^(3+)/Fe^(2+) (Ⅳ)

研究了波长、温度及表面处理对n-InP 光脉冲暂态行为的影响.结果表明.波长对时间常数无影响;随着温度升高,峰值下降,衰减变快.讨论了表面处理的影响,并对实验结果作了必要的解释.

In this paper the complex collection efficiency figures of n-InP in Fe^(8+)/Fe^(2+) solution are determined with light pulse technique by fast Fourier transformation using microcomputer. It is a half circle at fourth quadrant. According to theoratical model three photoelectrochemical kinetic parameters are calculated from the position of circle centre, the radius of circle and the characteristic frequency. Influences of the electrode potential and the light intensity on those parameters are dermined and the results are discussed.
