Antiperovskite Sr3 PbO thin films grown by molecular beam epitaxy
Abstract
Several antiperovskite compounds have recently been predicted to host bulk three dimensional Dirac dispersion as well as surface states protected by crystal symmetry. Here, we present fabrication of cubic antiperovskite Sr3PbO films epitaxially grown on LaAlO3 by molecular beam epitaxy. Fabricated films were capped with polymer without breaking vacuum to facilitate ex-situ transport characterization. All of the films showed metallic temperature dependence. The Hall effect measurement suggests that the carrier type is hole, whose density is around 5 ×1019 cm-3. Details of magnetotransport at low temperature is also described.
