Abstract
In this work, zinc selenide (ZnSe) nanowires were fabricated on indium-tin oxide coated glass substrate via template-assisted electrodeposition method from an electrolytic solution of zinc (II) sulphate (ZnSO4·7H2O) and selenium dioxide (SeO2). ZnSe nanowires of diameter 100 nm have been fabricated using polycarbonate track-etch membrane. Electrodeposition was done at 30 °C temperature and the length of the nanowires was controlled by adjusting the deposition time. Both morphological and electrical characteristics were studied. Sample characterization was done using scanning electron microscope and X-ray diffraction. I–V measurements reveal that the ZnSe nanowires have non-linear behavior like Schottky diode characteristics. Further, the ZnSe nanowires were used in astable multivibrator which acts as capacitor to give conventional output behavior. The temperature dependent capacitive properties of ZnSe nanowires reveal that ZnSe nanowire can be used as temperature sensor.
