N2 - We introduce the concept of topological invariants to nanophononics and implement a nanophononic semiconductor system supporting a robust topological interface state at 300GHz. We optically probe this mode through Brillouin spectroscopy and coherent phonon generation experiments. This type of topological interface states could become part of novel devices requiring resonant nanoacoustic structures such as compact integrated Brillouin light sources operating at ultrahigh frequencies.
