Temperature dependent optical properties of $ε$ -Ga $_{2}$ O $_{3}$ thin films

T. Makino, S. Yusa, D. Oka +1

We determined the complex dielectric functions of $ε$ -Ga $_{2}$ O $_{3}$ using optical transmittance and reflectance spectroscopies at temperatures from 10 K to room temperature…

Photoreflectance spectroscopy of BiOCl epitaxial thin films

T. Nishiwaki, T. Makino, Z. Sun +2

We have observed a new optical transition in the photoreflectance spectra of indirect-gap BiOCl thin films, which were grown on SrTiO $_{3}$ substrates. The position of this transitio…
