We report a comprehensive study of the gate induced electromodulated transmittance of infrared light by single-walled carbon nanotube (SWNT) thin films. The observed electromodulation is significantly enhanced by utilizing large diameter SWNTs, increasing the ratio of semiconducting to metal SWNTs and by decreasing the SWNT film thickness. The amplitude of the effect reported herein is more than an order of magnitude larger than in previous SWNT thin film solid state devices.
