Abstract
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..
