摘要：

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 AIN and GaN cylindrical nanowire structures.
