Photodetectors are one of the fundamental elements of optoelectronic circuits. Phototransistors produce current both by absorbing light and also taking advantage of the gate electrode to increase gain. Solution-processed electronics has many advantages, including low-cost and low-temperature fabrication. In thin-film transistors (TFTs), the channel can be made with carbon-based semiconductors such as carbon nanotubes (CNTs). […]
