Band structure engineering and interfacial buffer layers have been demonstrated as effective means to tune the Fermi level in topological insulators (TI). In particular, charge compensated compound (BixSb1-x)2Te3 (BST) plays a critical role molecular beam epitaxy growth of magnetic TIs. Here we introduce strategy exploiting epitaxial Cr2O3 layer amorphous capping BST films. These films exhibit ...

This work calculates the Lorentz–Lorenz coefficient with refractive index and density values of various molecules in their solid phase measured our laboratory under astrophysical conditions. was completed for a range temperatures from 13 K to close sublimation temperature each molecule. The studied were N2, CO2, NH3, CH4, CH3OH, C2H4, C2H6. For results match those found unique similar previous ...
