摘要: The photocurrent and spectral response characteristics of gallium arsenide (GaAs) are obtained by a multi-information measurement system, the evolution versus Cs:O flux ratio is investigated. experimental results show that increases approximately exponentially after first exposure to Cs until maximum sensitivity reached, detailed process ultimate different for samples. These differences analysed, according coadsorption oxygen on GaAs, an equation presented explain increase photocurrent.
