  Mixed dimensional hybrid structures have recently gained increasing attention
as promising building blocks for novel electronic and optoelectronic devices.
In this context, hybridization of semiconductor nanowires with two-dimensional
materials could offer new ways to control and modulate lasing at the nanoscale.
In this work, we deterministically fabricate hybrid mixed-dimensional
heterostructures composed of ZnO nanowires and MoS2 monolayers with micrometer
control over their relative position. First, we show that our deterministic
fabrication method does not degrade the optical properties of the ZnO
nanowires. Second, we demonstrate that the lasing wavelength of ZnO nanowires
can be tuned by several nanometers by hybridization with CVD-grown MoS2
monolayers. We assign this spectral shift of the lasing modes to an efficient
carrier transfer at the heterointerface and the subsequent increase of the
optical band gap in ZnO (Moss-Burstein effect).
