Paper Abstract

The response time of photoemissive materials is required for detecting ultrashort duration laser pulses. The photoelectron's response time will increase with increasing energy of photons. If the surface potential barrier of thin film declines, the photoemissive sensitivity or quantum yield will rise, however the response time will also increase which means that response time characteristic gets worse. As an example, the response time for Ag-O-Ca thin film is calculated.
