Modified electron-acoustic and lower-hybrid drift dissipative instability in a two-electron temperature plasma

Summary form only given, as follows. The author has considered a plasma model in which the electrons consist of two distinct groups, i.e. hot and cold. He has investigated analytically the drift dissipative instabilities of modified electron-acoustic and lower-hybrid waves in such a two-electron-temperature plasma. He has found that the modified electron-acoustic drift dissipative mode are strongly dependent on the number density of the cold electrons. From the expression for the growth rate, it is clear that these cold electrons can control the growth of this mode. However, the lower-hybrid drift-dissipative mode is nearly unaffected by these cold electron species.<>
