抄録

We demonstrate that, in a GaSb/GaAs epitaxial structure, a coherent longitudinal optical (LO) phonon in a GaAs buffer layer optically covered with a GaSb top layer is observed utilizing terahertz spectroscopy. It is confirmed from Raman scattering measurements that only the optical phonons in the GaSb layer is optically observable....
