电流随着温度改变当半导体受到热的影响的时候,随着它本身的温度的改变,它的导电能力有極大的改变。这是由于温度升高使半导休内的原子振动加强,使价电子获得等于或者大于激活能的能量,这样它就可以脱离它原来所屬的原子的束縛而成为自由电子,或者形成空穴。在这里,激活能就是指使价电子脱离原子束縛的能量。如果用能帶来表 Current changes with temperature When the semiconductor is affected by heat, its electrical conductivity changes greatly as its temperature changes. This is due to the increase in the temperature of the semi-conductive relaxation of the atomic vibration, so that the valence electron gain equal to or greater than the energy of the activation energy, so that it can be freed from the bound of its original atom to become free electrons, or the formation of holes. Here, activation energy refers to the energy that frees valence electrons from the bondage of atoms. If you can use to bring the table
