摘要

在HF:C2H5OH(1:3)电解液中，在n型GaAs上电化学生成多孔GaAs。采用干涉显微镜和扫描电镜对多孔砷化镓的表面形貌进行了研究。考察了总阻抗的谱图以及乙醇和丙酮蒸气对电荷转移的吸附影响。提出了利用多孔砷化镓的阻抗谱法检测不同气体的方法。

Using impedance porous GaAs-based for biomedical gas sensor

Porous GaAs was formed electrochemically on n-type GaAs in a HF:C2H5OH (1:3) electrolyte. The surface morphology of porous GaAs has been studied using interference microscope image and scanning electron microscope (SEM). The hodographs of the total impedance and the adsorption influence of ethanol and acetone vapor on the charge transfer were examined. The use of the impedance spectroscopy of porous GaAs for the detection of different gases was proposed.
