dc.description.abstractThe long-wave optical phonon frequencies of BexZn1-xO alloys are determined within the modified random-element isodisplacement model. The results indicate a two-mode behavior for A(1) and E-1 branches of the optical phonons. The dispersions of the interface and quasi-confined modes in the polar ZnO/BexZn1-xO quantum wells are calculated within the dielectric continuum model up to x = 0.2. In the absence of strain, the quantum wells yield as many as three distinct frequency ranges for the IF modes. However, the quasi-confined modes have two separate frequency ranges with boundaries determined by the ZnO-like and ZnO phonons. With the inclusion of strain, the boundaries of the frequency ranges for each mode are modified but without any change in the overall picture. (C) 2020 Elsevier B.V. All rights reserved.en_US
