Abstract

A theoretical investigation of the photoelectric effect through dust charge fluctuation on the low frequency dust-lower-hybrid (DLH) mode has been done using fluid model of plasma. In this study collisional effects between charged and neutral particles and lighter particles streaming along the both external magnetic and electric fields are considered. It is assumed that dust grains are negatively charged. It has been observed that the DLH mode becomes unstable significantly due to photoelectric effect compared to the streaming and collisional effects.
