Abstract

The synthesis of a varistor powder based on ZnO is carried out with the further fabrication of a device structure within the framework of the sol-gel method. To monitor the processes occurring in the sol, the method of Fourier-transform infrared spectroscopy is used. Studies of the surface structure of the material are carried out using scanning electron microscopy. The constructed current–voltage characteristic of the varistor structure is nonlinear with a nonlinearity coefficient of 2.36. The use of the sol-gel method for the manufacture of devices of this type makes it possible to obtain a grain size of 0.25 μm and achieve a reduction in the sintering temperature to 900°C.

论变阻器结构用氧化锌半导体粉末的溶胶-凝胶合成

在溶胶-凝胶法的框架内合成了一种基于氧化锌的变阻器粉末，并进一步制造了一种器件结构。为了监测溶胶中发生的过程，使用了傅立叶变换红外光谱法。此外，还使用扫描电子显微镜对材料的表面结构进行了研究。压敏电阻结构的电流-电压特性为非线性，非线性系数为 2.36。使用溶胶-凝胶法制造这种类型的器件，可以获得 0.25 μm 的晶粒尺寸，并将烧结温度降低到 900°C。
