Single‐walled carbon nanotube (CNT) films are transparent, conductive, and flexible materials. These films have uniform physical and electronic properties, and can be mass produced in a cost effective manner. Due to these favorable properties, they have been suggested for various applications such as flexible microelectronics, optoelectronic and photovoltaic devices, supercapacitors and chemical sensors. However, the percolative electronic transport phenomena in these films have not been thoroughly studied. In addition, for applications such as solar cells and photodetectors, the interface between the CNT film and the host material needs to be analyzed as it plays a significant role in determining the transport mechanisms and device characteristics. In this talk, we will
discuss our experimental and computational results on CNT film resistivity and 1/f noise scaling with device parameters. Then, we will analyze a metal‐semiconductor photodetector with CNT film as the metal and Si as the semiconducting substrate.
