Abstract

We present a model calculation o-f energy loss function for intralayer as well as interlayer interaction in modulation doped GaAs/AlGaiAs superlattice which consists of two GaAs layer at a distance d1 apart in a unit cell of length d. The intralayer interaction yields one acoustic and one optic plasmon modes while interlayer interaction gives only one. optic plasmon mode. The acoustic plasmon mode ceases to exist for very small values of wave vector and very large values of damping constant.
