If an electron with k state is initially in one miniband, elastic scattering will make the difference of the probability band occupation tend to zero . if electrons initially are located at a single wannier state, elastic scattering will make the difference of the probability band occupation tend to a constant which does not equal zero . the stable distribution in k space is just the same as the average distribution when no scattering 發(fā)現(xiàn)彈性散射會破壞電子間的關(guān)聯(lián),使得初始處在某一微帶上的態(tài)電子在兩微帶上的占有幾率趨于一致;初始電子處在實空間的單個瓦尼爾態(tài)上時,最后在彈性散射的影響下兩帶占有幾率差不為零,并且在上的穩(wěn)定分布和沒有散射時的平均分布相同。
