Fundamental absorption edges in heteroepitaxial YBiO${}_3$ thin films

Marcus Jenderka, Steffen Richter, Michael Lorenz +1

The dielectric function of heteroepitaxial YBiO${}_3$ grown on $a$-Al${}_2$O${}_3$ single crystals via pulsed laser deposition is determined in the spectral range from 0.03 eV to 4.5 eV…
