摘要

Highly transparent ring oscillators, exhibiting ~75% optical transmittance in the visible portion of the electromagnetic spectrum, are fabricated using indium gallium oxide as the active channel material and standard photolithography techniques. The n-channel indium gallium oxide transparent thin-film transistors (TTFTs) exhibit a peak incremental mobility of ~7 cm~2 V~(-1) s~(-1) and turn-on voltage of ~2 V. A five-stage ring oscillator circuit (which does not employ level-shifting) exhibits an oscillation frequency of ~2.2 kHz when the gate and drain of the load transistor are biased at 30 V; the maximum oscillation frequency observed is ~9.5 kHz, with the gate and drain of the load transistor biased at ~80 V.
