| Abstract: | The reflectivities of SbSI and their logarithmic derivatives between 1.8 and 4.5 eV have been measured at different temperatures. The structures in the reflectivities are compared with those calculated independently by the empirical pseudopotential method (EPM), using the pseudopotential form factors scaled from previous band structure calculations of other crystals. The large optical anisotropy of SbSI is explained. A preliminary band structure for SbSI is presented. |
