Abstract
A simple linear chain model is used to calculate the phonon dispersion curves for a superlattice composed of one layer of GaSe and one layer of InSe alternatively stacked along the c-axis. The resultant acousti c modes are essentially averages of the two constituents. Most optical modes are found to be confined in either GaSe layers of InSe layers. However, some low energy-optical modes have contributions from the two constituents.
