Lattice dynamics and polarization-dependent phonon damping in $\alpha$-phase FeSi${}_2$ nanoislands

J. Kalt, M. Sternik, B. Krause +16

We determined the lattice dynamics of metastable, surface-stabilized $\alpha$-phase FeSi${}_2$ nanoislands epitaxially grown on the Si(111) surface with average heights and widths ranging…
