Unusually large enhancement of thermopower in an electric field induced two-dimensional electron gas
Hiromichi Ohta, Taku Mizuno, Shijian Zheng +6
Two-dimensionally confined electrons showing unusually large thermopower (S) have attracted attention as a potential approach for developing high performance thermoelectric materia…
Electric field thermopower modulation analysis of an interfacial conducting layer formed between Y2O3 and rutile TiO2
Taku Mizuno, Yuki Nagao, Akira Yoshikawa +4
Electric field modulation analysis of thermopower (S) - carrier concentration (n) relation of a bilayer laminate structure composed of a 1.5-nm thick conducting layer, probably Tin…
Field-induced water electrolysis switches an oxide semiconductor from an insulator to a metal
Hiromichi Ohta, Yukio Sato, Takeharu Kato +4
Here we demonstrate that water-infiltrated nanoporous glass electrically switches an oxide semiconductor from an insulator to metal. We fabricated the field effect transistor struc…
Electric field modulation of thermopower for transparent amorphous oxide thin film transistors
Hirotaka Koide, Yuki Nagao, Kunihito Koumoto +5
To clarify the electronic density of states (DOS) around the conduction band bottom for state of the art transparent amorphous oxide semiconductors (TAOSs), InGaZnO4 and In2MgO4, w…
Experimental characterization of the electronic structure of anatase TiO2: Thermopower modulation
Yuki Nagao, Akira Yoshikawa, Kunihito Koumoto +3
Thermopower (S) for anatase TiO2 epitaxial films (n3D: 1E17-1E21 /cm3) and the gate voltage (Vg) dependence of S for thin film transistors (TFTs) based on TiO2 films were investiga…
A Single-Crystalline, Epitaxial SrTiO3 Thin-Film Transistor
Kosuke Uchida, Akira Yoshikawa, Kunihito Koumoto +3
We report herein fabrication and characterization of a thin-film transistor (TFT) using single-crystalline, epitaxial SrTiO3 film, which was grown by a pulsed laser deposition tech…
