摘要:

AbstractInterest in diamond‐like carbon (DLC) thin films has increased considerably in the last few years. It is suggested that DLC films may be used for electronic devices, especially working at high temperatures. The subject of this contribution is the electrical conduction of a metal/DLC/ Si system. The investigated DLC films were prepared by two methods: radio‐frequency plasma chemical vapour deposition (RF‐PCVD) and pulsed cathodic‐arc discharge (PCAD) on silicon substrates. The metal/DLC/silicon heterojunctions show rectifying characteristics. The rectifying character of the current‐voltage behaviour may be caused by a thin Interfacial SiO2sublayer existing between the DLC film an

摘要:

AbstractCharge carrier photogeneration in titanyl phthalocyanine was investigated by means of fluorescence and photocurrent measurements, under sample excitation by two time‐separated ultrashort light pulses. Exciton‐exciton annihilation was employed to obtain information on the time course of the fluorescence and generation processes. Charge carriers were found to be generated during only a short time interval after the exciton was created. This interval is much shorter than the fluorescence state lifet
