of the cirystal latt-ice (co-called lattice model in Vaich interaction wi-Lh the
internal field created by longitudinal and transverse vibrat can br-- taken
into account, in contrast to the conlUnuummodel where, rinly interaction with

Abstract: The POisson equation that must usually be solved in
handling actual problems in the physics of seLiiconductors is of
the form

approximate, being based on the condition? usva,liy realiz.
