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.
