▎ 摘 要
A high quality transparent p-n heterojunction device comprised of 1D zinc oxide (ZnO) nanorods (NRs) and an ultrathin 2D graphene oxide (GO): carbon nanotube (CNT) hybrid film was fabricated through a solution process. The turn on voltage and ideality factor of the device were 1.5V and 6.1, respectively. Optical measurements revealed that the UV absorption of the ZnO NRs increased after a GO: CNT hybrid film was spray-coated onto the NRs. As a result, the device exhibited a high response to UV illumination. The fabricated diode displayed high rectifying characteristics and excellent performance as a visible-blind UV sensor.
