MICRO-LEVEL PHOTOLUMINESCENCE AT LOW TEMPERATURE

Operation co-funded by EU cohesion policy (European Regional Development Fund (ERDF)) under the programme Multi-regional Spain - ERDF (2014ES16RFOP002), managing authority: Subdirección General de Gestión del FEDER, de la Dirección General de Fondos Europeos del Ministerio de Hacienda.. The source names no beneficiary for this operation. Location: Málaga Province (NUTS ES617); Spain. Budget: total eligible expenditure EUR 300,000; EU co-financing EUR 240,000 (co-financing rate 80%), as stated by the source. Runs 2018-01-01 to 2021-03-31. Source: Kohesio, EU cohesion policy projects managed by national and regional authorities (not CORDIS); selected because its summary names quantum technology. Summary from Kohesio (English machine translation by the source): Photoluminescence (PL) is applied to characterize materials and devices. Parameters such as of IQ quantum well (QW) can be measured for patterned structures using selective optical excitation of microstructures made from these materials. Selective excitation means precise fine control of the laser excitation beam size and positioning and the visualization of the sample under measurement. In general, that information can only be revealed at low temperatures. Therefore the PL measurement system must be compatible with a cryostat of He. PL is a robust, non- contact, non-destructive optical technique. Geometrical accuracy of the device requires mapping PL over the entire device or at least a region of interest on the device. A PL system must include a vision camera, so the user always sees the region of the wafer under excitation, useful when the wafer has patterned structures. So, the head must directly couple to a triple-grating spectrometer, ensuring the highest throughput and wide spectral coverage (200¿1600 nm). Moreover, can also use different excitation-laser wavelengths, and includes an assortment of motorized xyz-stages
