Calculation of the spectra of characteristic
electron losses in indium bromide
1Lviv State Agrarian University, 79240 Lviv-Dublyany, Ukraine
Abstract. For the first time, the fundamental optical functions of single crystals of
layered indium bromide are calculated on the basis of polarization-dependent reflection
spectra at the liquid helium temperature in the energy region of 2−30 eV. Features of the
spectra of bulk and surface characteristic losses are examined, and the bulk and surface
plasmon energies have been obtained. The identification of the genetic origin of the
principal structures in the spectra is accomplished. The correlation between the energies
of long-wave plasmons and the energies of reflectivity minimum has been determined.
Keywords: surface and bulk plasmons, reflection.
