用全带 Monte Carlo方法模拟了纤锌矿 Zn O材料电子的稳态和瞬态输运特性 .稳态输运特性包括稳态平均漂移速度 -电场特性、电子平均能量 -电场特性和在不同电场下电子按能量的分布 .在平均漂移速度 -电场特性中发现了微分负阻效应 .Zn O的瞬态输运特性包括平均漂移速度 -位移关系曲线、渡越时间 -位移关系曲线等 .在平均漂移速度 -位移关系曲线中发现了过冲现象 ,这种现象是电子从低能谷到高能谷跃迁过程中的弛豫时间产生的 .
The full-band Monte Carlo method was used to simulate the steady-state and transient transport properties of wurtzite Zn O materials.The steady-state transport properties include steady-state mean drift velocity-electric field characteristics, electron average energy-electric field characteristics and electric field characteristics at different electric fields The distribution of the electron by the energy in the average drift velocity - electric field characteristics found in the differential negative resistance effect.Zn O transient transport characteristics including the average drift velocity - displacement curve, transit time - displacement curve, etc. In the average The overshoot phenomenon was found in the drift velocity-displacement curve, which is caused by the relaxation time of the electron from the low energy valley to the high energy valley transition.
