Hybrid flexible vertical nanoscale diodes prepared at low temperature in large area.

Fabrication and operation of hybrid flexible vertical nanoscale diodes are reported. The diodes, formed by n-type ZnO and p-type CuSCN, were embedded in a 6 µm polymer foil, provided with vertical cylindrical openings of about 100 nm, by using a low temperature solution based electrochemical deposition technique. Electrical measurements show diode function with sound device characteristics at operation temperatures up to 67 °C. This heterojunction shows the potential for ZnO based ultraviolet light-emitting diodes.
