Abstract

In this work, the BP method was used and modeled on ICT in order to calculate
the energy levels of electron in the КН for calculating polyaron effects , and the image of
the compressive potential of the КН was considered parabolic. Because of the difficulty of
solving the differential equation (6), its solution is sometimes used by linear combinations
of specific solutions which are obtained in strong and weak interaction regimes. When this
method is applied to the volumetric polar semiconductors, the interpolation estimation of
the energy of polaron state is obtained. In this case the correction due to the polaron effect
occurs in the regime of a strong interaction impact Α > Α (~ 6 · ·8) 
,
in this condition the
electron wave function is localized in the polarization field. In the field c  Α<Α
,
the
electron-wave function is in the extended state (delocalized), and the polaron state energy
suits the Lee-Loue-Pains result, namely it is proportional to the Α .
