Fabrication and characterization of transparent n-ZnS/p-diamond film heterojunction

► We prepare transparent n-ZnS/p-diamond heterojunction diodes. ► The diode shows rectifying behavior with turn-on voltage of ~ 1.1 V. ► The current transport mechanism depends on applied bias voltages. ► The diode has a broad transparent band from 500 nm to 800 nm region.
