Journal ArticleDOI
Direct Actuation of GaAs Membrane with the Microprobe of Scanning Probe Microscopy
Kojiro Tamaru,Kojiro Tamaru,Keiichiro Nonaka,Keiichiro Nonaka,Masao Nagase,Hiroshi Yamaguchi,Shin'ichi Warisawa,Sunao Ishihara +7 more
TL;DR: In this paper, a method for evaluating the dynamic characteristics of micro-and nanoresonators with high spatial resolution is proposed, where the mechanical resonance of circular micrombrane resonators is directly induced by voltage applied from the microprobe of a scanning probe microscopy (SPM) system.
Journal ArticleDOI
Magneto-optical spectroscopy of excitons and trions in charge-tunable quantum dots
Haruki Sanada,Tetsuomi Sogawa,Hideki Gotoh,Yasuhiro Tokura,Hiroshi Yamaguchi,Hayato Nakano,Hidehiko Kamada +6 more
TL;DR: In this article, the magneto-optical properties of charge-tunable GaAs quantum dots (QDs) were investigated, and the effects of electron-electron and electron-hole interactions on shell and spin configurations of excited trions were discussed.
Journal ArticleDOI
First-principles calculations on atomic and electronic structures of misfit dislocations in InAs/GaAs(1 1 0) and GaAs/InAs(1 1 0) heteroepitaxies
TL;DR: In this paper, the atomic and electronic structures of the misfit dislocations of InAs/GaAs(1/1/0) and GaAs/InAs( 1/1 /0) heterointerfaces were investigated by first-principles calculations and scanning tunneling microscopy (STM).
Journal ArticleDOI
Optically induced strong intermodal coupling in mechanical resonators at room temperature
TL;DR: In this article, the photothermal effect in thin membrane structures was used to demonstrate strong parametric mode coupling in mechanical resonators at room temperature by using photothermal effects in thin membranes.
Journal ArticleDOI
High-Field/Multi-Frequency ESR Measurements on the Triangular Lattice Antiferromagnet CuFeO 2
Shojiro Kimura,N. Nishihagi,Hiroshi Yamaguchi,T. Kashiwagi,M. Hagiwara,Noriki Terada,K. Kindo +6 more
TL;DR: In this article, the authors performed multi-frequency ESR measurements on the geometry frustrated triangular lattice antiferromagnet CuFeO2 and analyzed the observed ESR modes based on a mean field theory.
