摘要
Silicon nanowire photodetectors were fabricated for large area digital imaging applications. An array of silicon nanowires fabricated by plasma enhanced chemical vapor deposition (PECVD) was incorporated into lateral metal-semiconductor-metal (MSM) photodetectors with 2 mu m electrode spacing. A collection efficiency of up to 0.36 and responsivity of 0.136 was measured using an applied bias of -10V. The rise time in response to a blue LED light source was measured to be 35.2 mu s.
