半导体超晶格的介电函数倒数与快速电子能量损失谱
INVERSE DIELECTRIC FUNCTION AND FAST ELECTRON ENERGY-LOSS-SPECTRUM OF SEMICONDUCTOR SUPERLATTICES
【摘要】 我们计入相邻量子阱间的电子隧穿效应,得到了半导体超晶格的介电函数倒数的表式,计算了它的快速电子能量损失谱,表明电子遂穿效应使快速电子能量损失增大。
【Abstract】 The inverse dielectric function of semiconductor superlattices is derived with inclusion of tunneling effects between adjacent quantum wells. The result is, then, used to evaluate the fast electron energy-loss-spotrum with the conclusion that tunneling effect tend to enhance the energy loss in superlattices.
