Vm. Yakovenko et al., INTERACTION OF CHARGED-PARTICLE FLOWS WITH PLASMONS IN 2-DIMENSIONAL ELECTRON-GAS, International journal of infrared and millimeter waves, 17(3), 1996, pp. 559-568
The theory of interaction of charged particle beams with 2D electron g
as, located in the field of the delta-lib potential wall U(y) = U-0 de
lta(y) has been developed. The kinetic equation for plasmons in 2D ele
ctron gas was obtained; the conditions of arising of their instability
are given and the corresponding expressions for the increment of plas
mons are found.
