ABSTRACT
By employing a quantum hydrodynamic model for bounded three-component quantum plasmas, two kinds of streaming instabilities due to ion-streaming and dust-streaming are studied. For this purpose, the dispersion relation for the bounded wave in quantum electron-ion-dust plasmas is obtained by carrying out a normal mode analysis. The results of theoretical analysis and numerical simulation show that the streaming speeds, the boundary conditions, and the quantum parameters strongly influence the instabilities. In particular, it is found that the boundary effect and the quantum effect are closely coupled, i.e., the quantum effect depends on the geometry parameters.
