Flexible Transparent Field-Effect Diodes Fabricated at Low-Temperature with All-Oxide Materials

Flexible fully transparent diodes with high rectification ratio of 5 × 108 are fabricated with all-oxide materials at low temperature. The devices are optically transparent in the visible spectra range and electrically robust under mechanically bending. Distinguished from other diodes, these diodes utilize diode-connected thin-film transistor architecture and follow field-effect principles.
