Abstract: (661 Views)
In this research, we have investigated analytically the changes in the acoustic waves gain across a solid-state medium using quantum fluid equations. First, by considering the corrections caused by the quantum fluctuation in the density of current carriers, we have obtained the wave dispersion relation and then we calculated the gain coefficient. Analytical and numerical results show that changes in wave frequency and drift velocity of carriers affect the acoustic waves gain and the presence of positive current carriers reduces the gain coefficient.
