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…
