Abstract

This work reports the copper oxide (CuO) single nanowire (SNW) based devices for the detection of volatile organic compounds (VOCs). Fabrication involves the synthesis of CuO nanowires by thermal oxidation of copper. The SNW back-to-back Schottky diode electrodes are fabricated by microcantilever contact print (

$\mu$

CCP) of silver nanoparticles (AgNP) on Si-SiO

$_{2}$

substrate. Devices with channel lengths 10, 20, and 30

$\mu$

m are employed to detect VOCs such as ethanol, acetone, and 2-propanol, etc., with concentrations ranging from 25–100 ppm. Sensing is carried out at room temperature, 150

$^{\circ }$

C, and in white light (1 mWcm

$^{-2}$

). The device exhibits a maximum response of 1.1% and 4.86% under various operating conditions with a limit of detection (LOD) of 15.4 ppm. The device has limited performance, but is stable for four months.

用于挥发性有机化合物(VOCs)检测的CuO单纳米线印刷器件

本文报道了基于氧化铜(CuO)单纳米线(SNW)的挥发性有机化合物(VOCs)检测装置。制造涉及到铜的热氧化合成氧化铜纳米线。在Si-SiO $_{2}$衬底上采用微悬臂接触印刷($\mu$CCP)法制备了SNW背对背肖特基二极管电极。通道长度为10、20和30 $\mu$m的设备用于检测浓度范围为25-100 ppm的voc，如乙醇、丙酮和2-丙醇等。传感在室温，150°C，白光(1 mWcm$^{-2}$)下进行。该器件在各种工况下的最大响应分别为1.1%和4.86%，检出限为15.4 ppm。该设备性能有限，但可以稳定运行4个月。
