英文摘要	Carbon nanotube (CNT) diodes with different channel length between L = 0.6 mu m to 3.5 mu m are fabricated on the same tube, and the electric and photovoltaic characteristics are investigated. It is found that although the open voltage of the diode increases rapidly for channel length L less than 1.0 mu m, it saturates for longer channel devices. On the other hand, the short circuit current of the diode exhibites a clear peak at intermediate channel length of about 1.5 mu m, a large leakage current via tunneling for short channel device and significantly decreased current for long channel device due to the increased recombination and channel resistance. The optimal channel length for a CNT diode in photovoltaic application is thus determined to be about 1.5 mu m.; Nanoscience & Nanotechnology; Materials Science, Multidisciplinary; SCI(E); EI; PubMed; 5; ARTICLE; 3; 1154-1157; 4
