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…
Exotic radiation from a photonic crystal excited by an ultra-relativistic electron beam
N. Horiuchi, T. Ochiai, J. Inoue +9
We report the observation of an exotic radiation (unconventional Smith-Purcell radiation) from a one-dimensional photonic crystal. The physical origin of the exotic radiation is di…
Majority-Carrier Mobilities in Undoped and \textit{n}-type Doped ZnO Epitaxial Layers
T. Makino, Y. Segawa, A. Tsukazaki +2
Transparent and conductive ZnO:Ga thin films are prepared by laser molecular-beam epitaxy. Their electron properties were investigated by the temperature-dependent Hall-effect tech…
Analysis on reflection spectra in strained ZnO thin films
T. Makino, Y. Segawa, M. Kawasaki +1
Thin films of laser molecular-beam epitaxy grown ZnO films were studied with respect to their optical properties. 4-K reflectivity was used to analyze various samples grown at diff…
Spectral shape analysis of ultraviolet luminescence in \textit{n}-type ZnO:Ga
T. Makino, Y. Segawa, S. Yoshida +4
Thin films of laser molecular-beam epitaxy grown \textit{n}-type Ga-doped ZnO were investigated with respect to their optical properties. Intense room-temperature photoluminescence…
