Transition-metal dichalcogenide (TMD) monolayers combined with zinc-oxide (ZnO) nanowires (NW) represent a promising platform for electrically tunable nanophotonic devices. ZnO NWs can be used as nanoscale lasers, supporting waveguiding, field amplification and being the gain medium at the same time. A further major step towards the success and broad applicability of NW lasers, is the possibility to actively tune their laser properties via external stimuli, such as the piezo-electric effect[1]. Recently, we have demonstrated that coupling of ZnO NWs to monolayer TMDs leads to an increase of the lasing intensity threshold[2]. Building on this approach, in this poster I will propose a device where the laser emission of a ZnO NW can be electrically tuned by coupling it to a TMD based field-effect transistor.
Besides the main idea and device architecture, I will present preliminary results of device fabrication and characterization.
