Temperature dependent optical properties of -GaO thin films
T. Makino, S. Yusa, D. Oka +1
We determined the complex dielectric functions of -GaO using optical transmittance and reflectance spectroscopies at temperatures from 10 K to room temperature…
Optical Properties of LiNbO thin films
T. Kurachi, T. Yamaguchi, E. Kobayashi +3
The complex dielectric functions of LiNbO were determined using optical transmittance and reflectance spectroscopies at room temperature. The measured dielectric function spect…
Magneto-photoluminescence of charged excitons from MgZnO/ZnO heterojunctions
T. Makino, Y. Segawa, A. Tsukazaki +5
We report on the photoluminescence (PL) properties of MgZnO/ZnO heterojunctions grown by plasma-assisted molecular-beam epitaxy. Influence of the applied magnetic field (B) on the…
Precise calibration of Mg concentration in MgxZn1-xO thin films grown on ZnO substrates
Y. Kozuka, J. Falson, Y. Segawa +3
The growth techniques for MgxZn1-xO thin films have advanced at a rapid pace in recent years, enabling the application of this material to a wide range of optical and electrical ap…
Ultrafast optical control of magnetization in EuO thin films
T. Makino, F. Liu, T. Yamasaki +6
All-optical pump-probe detection of magnetization precession has been performed for ferromagnetic EuO thin films at 10 K. We demonstrate that the circularly-polarized light can be…
Optical properties of \textit{n}- and \textit{p}-type ZnO thin films -- two different approaches to the impurity distribution inhomogeneity
Takayuki Makino
We investigated the optical properties of epitaxial \textit{n}- and \textit{p}-type ZnO films grown on lattice-matched ScAlMgO substrates. Chemical doping yielded a severe inho…
