The dependence of grain boundary on conductivity in NTC polycrystalline oxide semiconductor was discussed.
主要讨论NTC多晶氧化物半导体中晶界对电导的影响。
The grain resistance and the grain boundary resistance decrease with increase of temperature, so that the electrical conductivity is improved.
随着温度升高，晶粒电阻和晶界电阻逐渐降低，导电性更强。
Conductivity varies with grain size of GDC films due to the grain boundary space charge effect, the smaller the grain size, the higher the conductivity and vice versa.
晶界空间电荷效应导致GD C薄膜电导率随晶粒尺寸而变化，晶粒尺寸越小，电导率越大。
