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…
Optical Properties of ZnO-based Quantum Structures
Takayuki Makino
The optical properties of ZnO quantum wells, which have potential application of short-wavelength semiconductor laser utilizing a high-density excitonic effect, were investigated.…
Electron transport in ZnO thin films
T. Makino, Y. Segawa, A. Tsukazaki +2
Epitaxial, n-type ZnO films grown by a laser molecular-beam epitaxy method were investigated by the temperature-dependent Hall-effect technique. The 300-K carrier concentration and…
Exciton-optical-phonon coupling: comparison with experiments for ZnO quantum wells
T. Makino, Y. Segawa, M. Kawasaki
The temperature-dependent linewidths of excitons in ZnO quantum wells were studied by measuring absorption spectra from 5 K to room temperature. We deduced experimentally the excit…
