研究了处在一维渐近周期势vn=vcos(Qn+anv)(0<λ<1)中运动的电子态的特性,从理论上分析了Q=2π/4时,扩展态和局域态存在的条件,解析地得到了迁移率边界的值。
2)  mobility edges
迁移率边
1.
mobility edges, critical exponents.
我们利用Participation Ratio(PR),Inverse ParticipationRatio(IPR)和局域化长度ξ仔细讨论了无序与关联之间的竞争,并重点考虑了与金属——非金属态转变相关的结果,特别是临界参数,比如迁移率边、临界指数等。
3)  Grain Boundary Mobility
晶界迁移率
4)  grain boundary migration
晶界迁移
1.
The results showed that a compressive strain parallel to the grain boundary enhanced the grain boundary migration,which is driven by the interaction between neighboring grain boundaries.

CAS号:

性质:β粒子与载气氩分子间的碰撞是弹性的,而与试样分子间的碰撞则是非弹性的,即总伴有能量损失。适当选择脉冲持续时间,使快电子能够完全到达正极,而慢电子则不能到达。当试样进入后,快电子所产生的电流就会改变,从而输出信号。
