One dimensional (1D) Schottky diodes between metals and carbon nanotubes (CNTs) can separate the photo-generated electron-hole (e-h) pairs in order to produce photocurrent in the CNT infrared (IR) sensors for detection and quantification. However, the traditional Schottky barrier theories developed for the metal and planar semiconductor contacts are different from the contacts between metal and CNT...
Carbon nanotube (CNT) based infrared (IR) detectors have been reported and shown promising properties taking advantage of its one dimensional structure and unique electrical properties. The CNT photodiodes detect IR signal through Schottky barriers that are formed when metal and semiconductor CNT come into contact due to the difference of the energy levels. However, the generated photocurrent was...
