ZnO subwavelength wires for fast-response mid-infrared detection.
نویسندگان
چکیده
Room temperature operating thermal detection for mid-infrared light based on ZnO subwavelength wires has been demonstrated. Electric resistance in ZnO wires increases linearly with the intensity of incident light. Noise equivalent power (NEP) of 5.8 microW/Hz(1/2) (at 1 kHz) with typical response times as fast as 1.3 ms is obtained at 10.6-microm wavelength. The sensitivity and response time of the detector are also found to be insensitive to the ambient.
