摘      要：In this paper,the Dyakonov-Shur instability of terahertz(THz)plasma waves has been analyzed in gated cylindrical field effect transistor(FET).In the cylindrical FET,the hydrodynamic equations in cylindrical coordinates are used to describe the THz plasma wave in twodimensional electronic *** research results show that the oscillation frequency of the THz plasma wave is increased by increasing the component of wave in the circumferential direction,but in stability increment of the THz plasma wave are in creased by increasing the radius of channel.
