Transferable ZTO Micro-Spheres Monolayer Based UV Photodetectors
View through CrossRef
Zinc-tin-oxide (ZTO) is very attractive materials due to similar optical and electrical properites to those of ZnO. In addtion, the morphology control of ZTO nanomaterials such as nanowires, cubu, sphers etc is possible by using solution based synthesis methods. In this presentation, we reprot on the metal-semiconductor-metal (MSM) UV photodetectors consisting of transferable ZTO microspheres (MSs) monolayer with different phases. To investigate the effects of different phases of ZTO MS on the UV detection performance, the transferrable amorphous ZnSnO3 (a-ZTO) and crystallized Zn2SnO4 (c-ZTO) MSs monolayer were formed. From the fabricated UV detectors with different phases, c-ZTO MS monolayer based photodetectors are superior to a-ZTO base ones in device performance . The external quantum efficiency of c-ZTO MS based UV photodetector shown 580.9% (at 310nm) and the UV-to-visible rejection ratio of the c-ZTO exhibited over 1400, which indicated that our fabricated ZTO MS UV photodetectors have great visible-blind properties. For the further improvement of optoelectronic device performances, the c-ZTO MS-based UV photodetectors was optimized using with various sphere’s diameters. Our suggested facile transferable ZTO MS monolayer based optoelectronic devices have excellent potential to open a new way for various photonic and electronic applications
