Journal ArticleDOI
Field-Effect Transistor with Deposited Graphite Thin Film
TL;DR: In this paper, the field effect of graphite-rich carbon nanocrystallite thin films deposited by electron cyclotron resonance sputtering was investigated, and an appreciable ambipolar field effect was observed at the film edge where the thickness was vanishing.
Journal ArticleDOI
Electron beam lithography on vertical side faces of micrometer-order Si block
Kenji Yamazaki,Hiroshi Yamaguchi +1 more
TL;DR: In this paper, a 3D electron beam (EB) nanolithography on resist films coated on vertical side faces of Si blocks with micrometer-order size is demonstrated by combining the original three-dimensional EB writing technique with a newly developed low-viscosity resist solution.
Journal ArticleDOI
Observing the semiconducting band-gap alignment of MoS2 layers of different atomic thicknesses using a MoS2/SiO2/Si heterojunction tunnel diode
Katsuhiko Nishiguchi,Andres Castellanos-Gomez,Hiroshi Yamaguchi,Akira Fujiwara,Herre S. J. van der Zant,Gary A. Steele +5 more
TL;DR: In this paper, the authors demonstrate a tunnel diode composed of a vertical MoS2/SiO2//Si heterostructure, where a thin gate oxide allows tunneling current to flow between the n-type MoS 2 layers and p-type Si channel.
Journal ArticleDOI
Use of adenosine (5')polyphospho(5')pyridoxals to study the substrate-binding region of glutathione synthetase from Escherichia coli B.
Takao Hibi,Hiroaki Kato,Takaaki Nishioka,Jun'ichi Oda,Hiroshi Yamaguchi,Yukiteru Katsube,Katsuyuki Tanizawa,Toshio Fukui +7 more
TL;DR: Results demonstrate the bivalent binding of AP4-PL lying across the gamma-glutamylcysteine- and ATP-binding sites of the glutathione synthetase.
Journal ArticleDOI
Controlling Quality Factor in Micromechanical Resonators by Carrier Excitation
Hajime Okamoto,Daisuke Ito,Daisuke Ito,Koji Onomitsu,Tetsuomi Sogawa,Hiroshi Yamaguchi,Hiroshi Yamaguchi +6 more
TL;DR: The quality factor of GaAs microcantilevers consisting of Si-doped and undoped GaAs layers can be controlled by tuning the wavelength of the incident laser used for carrier excitation as discussed by the authors.
