In the weak intensity range, the photoresponse decreases linearly with the light intensity and the relaxation time of the photoresponse becomes larger.
在弱光范围,光响应随光强的变小呈线性减弱,且光响应的弛豫时间变长。
The Cobalt electrode does not show photoresponse in the positive scan while it shows P-type photoresponse in the negative scan.
