Molecular Beam Epitaxy Growth and Characterization of Thin ...

Thin layers of single-crystal, epitaxial semiconductor tin (α-Sn) were grown by molecular beam epitaxy (MBE) on cadmium telluride (CdTe) substrates. X-ray diffraction and Raman scattering measurements confirm that the thin layers of α-Sn are slightly strained, which supports theoretical prediction that α-Sn is a 3-D topological insulator (TI).
