The electron-phonon interaction in ternary mixed crystal of zinc compounds is studied. The electron-phonon interaction Hamiltonian including the unit-cell volume variation in ternary mixed crystals is obtained by using the modified random element isodisplacement model and Born-Huang method. The polaronic self-trapping energy and renormalized effective mass of ZnSexTe1-x, ZnSxSe1-x and ZnSxTe1-x compounds are numerically calculated. It is confirmed theoretically that the nonlinear variation of the self-trapping energy and effective mass with the composition is essential and the unit-cell volume effects cannot be neglected except the week e-p coupling. The deducting dimension of the mixed crystal strengthening the nonlinearity and volume effects..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
