CuPc based organic--inorganic hetero-junction with Au electrodes
CuPc based organic-inorganic hetero-junction with Au electrodes

A hetero-junction of n-silicon (n-Si) and copper phthalocyanine (CuPc) has been fabricated. The current--voltage characteristics were investigated to explain the rectification and conduction mechanism. The effect of temperature and humidity on the electrical properties of n-Si/CuPc hetero-junction has also been investigated. The characteristics of the junction have been observed to be temperature and humidity dependent, so it is suggested that this junction can be used as a temperature and humidity sensor.
