 Notes
Abstract: In this paper, Schottky-like behavior of single-walled carbon nanotube (SWNT) film contacts on Ge is demonstrated by the fabrication and electrical characterization of metal-semiconductor-metal (MSM) photodetectors with SWNT film electrodes. In addition, the effect of device geometry on the dark current is studied by scaling the active area, finger width, and finger spacing of the MSM photodetectors. Finally, the dark current of the SWNT film devices is compared to the dark current of metal control samples, demonstrating that the use of SWNT film electrodes results in a significant reduction in dark current. These experimental results give insight into the electrical properties of the SWNT film-Ge interface while also demonstrating the use of SWNT film as a transparent and conductive material for electronic applications.
