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…
