Our Techniques Room Temperature & Cryogenic Photoluminescence and Raman Spectroscopy Setups In the Nano-spectroscopy Lab we do spectroscopy at the nanoscale on nanostructures. We are expert in the design and realization of customized advanced optical spectroscopy setups for photoluminescence, absorption, and Raman measurements performed in a spatially-resolved manner on single nanostructures. We are able to work at the edge of the light diffraction limit or to beat it with several techniques, such as beam shaping or coupling to AFM tips (near-field optical microscopy), achieving a 50-100 nm spatial resolution. Low-temperature Spectroscopy Setup We have room temperature and cryogenic (closed-cycle cryo-free cryostat) setups, both with positioning accuracy of 50 nm. We apply optical techniques under different experimental conditions (varying excitation power density, sample temperature, light polarization, magnetic fields). By creating our customized setups we maximize signal-to-noise ratio with respect to commercial setups. Tunable Excitation Light We have three extra narrow-band continuous wave lasers and one pulsed light source with tunable wavelength (450-1100 nm) and tunable repetition rate. We have spectrometers and detectors to detect signal from 450 nm to 2100 nm. Second-order autocorrelation Setup We can perform also second-order autocorrelation measurements under continuous wave or pulsed excitation, as well as time resolved photoluminescence spectroscopy. Micromanipulation Setup We are specialized in the micro-manipulation of single nanostructures under optical microscope, and in the integration of nanostructures into new devices. For transfering our low dimensional materials, such as flakes, we have access to the Department facilities coupled to anaerobic chamber. Micromanipulators equipped with tips for fine nanowire placement To perform pick-and-place techniques with nanowires we employ glass or metal needles (100 nm to 500 nm of tip radius). Nanowire on TEM Grid Pick-and-place allows to pick up selected nanowires from the growth chip and transfer them to TEM grids for further investigation.

ERC Project The group hosts the ERC Starting grant of Marta De Luca. NANOWHYR: Dots-in-NANOWires by near-field illumination: novel single-photon sources for HYbRid quantum photonic circuits The project aims at creating movable quantum light emitters for photonic circuits. In silicon-based quantum photonic circuits, a significant challenge is the efficient integration of a III-V-based single photon source. We are utilizing semiconductor nanowires because they can be grown directly on silicon or transferred to it after growth. When a nanowire incorporates a single photon emitter, such as a quantum dot, it becomes a movable light source. We are exploring the fabrication of quantum light emitters via a combination of hydrogenation and near-field illumination. This method enables the creation of an arbitrary number of quantum light emitters, which can be controlled in energy and position, allowing for integration in cavities.
