Abstract:With the help of linear composed operators of electronic momentum and coordination the effect of electric field on interface polaron is studied in this paper. The reciprocal radius, ground state energy and effective mass of interface polaron were calculated. When the direction of electric field is from the crystal with larger dielectric constant to the crystal with smaller dielectric constant, appling electric field is favorable to form interface polaron. Analytics and numerical results are given, respectively, in this paper for weak and moderate electric field. These results are helpful for explaining the behavior of interface polaron in the electric field.

 

Key words: polaron interface polar crystal ground state energy
