摘要

利用预处理的碳纤维为模板

在325 nm激光照射下

该器件显示出约200倍的光电流增益

且具有良好的稳定性和光谱选择性。文中同时对响应机理进行了讨论。

Abstract

Brush-like hierarchical ZnO nanostructures on carbon fiber was fabricated by RF magnetic sputtering method and hydrothermal growth. The hybrid structures showed high surface-to-volume ratio and better electrical conductivity. An individual carbon fiber coated ZnO nanorods was transferred to the Au interdigital electrodes to form an ultraviolet photodetector

and the spacing of the electrodes is 180m. Under the illumination of 325 nm UV light

the device shows a high photocurrent gain of 200

a good stability and the spectral responsivities. Furthermore

the mechanism for UV response is discussed.
