Superlattices exhibit desirable electronic properties such as resonant tunneling. However, there is a high technology barrier for fabricating such structures, using methods such as molecular beam epitaxy (MBE). We fabricated multilayer structures of

We investigated the response time of a-Se based vacuum photodetector driven by diamond cold cathode. To characterize the response time, the a-Se surface was illuminated using pulsating white light and the variation of emission current from diamond fi
