This project aims to develop software for automatic reading of spectra from a CCD camera mounted on a spectrometer, which is a key element of the light detector optics that was installed in a low temperature tunneling scanning microscope (LT-STM). This system is basically composed of a parabolic mirror mounted on a nanomanipulator, a converging lens, an optical fiber beam, a spectrometer and a CCD camera. The challenge the student must overcome is to control the spectrometer and CCD, acquire spectra and synchronize this with the microscope imaging system. The acquisition of spectra must be synced with STM scanning and this is very important for the Young Researcher FAPESP project that enabled the purchase of LT-STM and whose ultimate goal is to study the luminescence of nanostructured semiconductors. This project mainly involves the issue of this synchronization and luminescence mapping measures in the STM. In addition, the student will work with the processing of acquired data using automated Python routines.
