Infrared spectroscopy (IRS)
The InfraRed Spectroscopy Group (IRS group) is a research team based at the Department of Physics of Sapienza University of Rome, Italy. The team is formed by university professors, post-doctoral researchers and doctoral students cooperatively working in the IRS laboratories, located at the fourth floor of the new Fermi Building of the “Dipartimento di Fisica” in the center of Rome, where both Enrico Fermi and Ettore Majorana have obtained part of their historical achievements.
The team is engaged in the investigation of solid-state materials, nanostructures and biological systems by optical spectroscopy from the very far-infrared range through the mid-infrared up to the ultraviolet. Broadband Fourier-transform spectroscopy is the main experimental tool, but grating spectrometers, infrared microscopes, quantum cascade lasers and terahertz amplifier-multiplier chains are all available in the IRS labs. Infrared synchrotron radiation, single-crystal and thin-film material growth, electromagnetic simulations and nanofabrication technologies are all accessed through long-standing national and international collaborations.
