Abstract
The presence of polar impurity species in nonpolar molecular materials may result in the appearance of traps for charge carriers. Calculations of local values of the polarization energy in the vicinity of a dipolar defect carried out on a simple cubic molecular lattice show that traps as deep as several tenths of an electron volt can result in such a way, their depths and cross sections depending on the dipole moments of the guest molecules
