Effect of Double Schottky Barrier in Gallium-Zinc-Oxide Thin Film

다국어 초록 (Multilingual Abstract)

This reports the electrical behavior, bonding structure and Schottky contact of gallium-zinc-oxide (GZO) thin film annealedat 100~400℃. The mobility of GZO with high density of PL spectra and crystal structure was also increased because of thestructural matching between GZO and Si substrate of a crystal structure. However, the GZO annealed at 200℃ with anamorphous structure had the highest mobility as a result of a band to band tunneling effect. The mobility of GZO treated atlow annealing temperatures under 200℃ increased at the GZO with an amorphous structure, but that at high temperaturesover 200℃ also increased when it was the GZO of a crystal structure. The mobility of GZO with a Schottky barrier (SB) wasmostly increased because of the effect of surface currents as well as the additional internal potential difference.
