The interaction of electron and the modulated acoustic phonon in free-standing cylindrical nanowire is investigated theoretically. The interaction Hamiltonian is derived by taking the divergence of the displacement vector of the acoustic phonon. The variational computations for the ground-state energy of the acoustic polaron in cylindrical nanowires are numerically performed for different cutoff wave-vectors. The electron and the hole are confirmed to have the self-trapping transition in both the AlN and GaN cylindrical nanowire structures..

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.
