✦ Synopsis

In this work, analytical solutions for the interface longitudinal-optical (LO) phonons in cylindrical polar-semiconductor quantum wires are normalized by the standard quantization condition. Two cases are considered: polar-semiconductor quantum wires encapsulated in another polar-semiconductor and polar-semiconductor quantum wires encapsulated in metal. For the case of metal encapsulation it is demonstrated that unwanted inelastic interface LO phonon scattering is eliminated since the interface modes do not satisfy the appropriate boundary conditions.
