Improving Raman spectra of pure silicon using super-resolved method

In this paper, we demonstrated a method to super-resolved Raman spectroscopy, which improves the resolution of pure silicon spectra. Experimental investigations were carried out on the spectra of pure silicon. A tunable Fabry-Perot (F-P) filter was added to the classical Raman setup in which measuring the spectra for different states of the F-P filter coupled with decoded experimental results yielded a spectrum of higher resolution having a reduced linewidth in the pure silicon spectrum. Therefore, this method can be very helpful for improving the detection of silicon material in nanostructures using a low resolution Raman spectroscopy system.
