Optical emission of monolayer-hybridized nanowire lasers — •Moritz Willems, Edwin Eobaldt, Alexander Zaunick, Aurelia Eberhard, Lukas Jäger, Xiao Chen, and Carsten Ronning — Friedrich Schiller Universität, Jena, Deutschland

Semiconductor Nanowires have attracted substantial scientific interest as foundation for nanoscale coherent light sources and all-optical circuits, based on to their remarkable waveguide properties and their intrinsic ability to lase. 2D-Materials offer a functional environment that enables influencing the lasing characteristics, including emission wavelength and lasing threshold, of ZnO nanowires. These hybrid structures thus allow for electrical and optical charge and energy transfer. Deterministic nanowire integration is achieved through stage-assisted transfer using PDMS and tip-assisted nanomanipulation. Comparative micro-photoluminescence measurements are used to investigate how the 2D-materials influence and modify the lasing behaviour of individual nanowires.
