Semiconductor nanowires have attracted great scientific attention due to their remarkable waveguiding properties and their intrinsic capability to lase under sufficiently high excitation, thus, paving the way towards nanoscaled coherent light sources and the realization of all-optical circuits. After the spectral and temporal characteristic of single nanowire lasers have been extensively studied during the past decade, today’s research focuses on their effective integration into functional and nanoscaled environments. In this regard, the hybridization of semiconductor nanowire lasers with two-dimensional materials could offer new capabilities for a dynamical emission tuning enabled by charge transfer processes at the heterointerface. As a proof of concept, hybrids systems containing ZnO nanowires on top of MoS2 monolayers were investigated by micro-photoluminescence measurements. By further adopting a deterministic transfer approach, it was possible to study hybridization-related changes of the lasing emission on one and the same nanowire.
