Rafael S. Alencar is an Associated Professor at the Physics Department of the Federal university of Pará (UFPA), Brazil. He received the Ph.D. degree in physics in 2016 at the Federal university of Ceará with one-year research stay at the Université Claude Bernard Lyon 1 – Institut Lumière Matière (ILM), France, with emphasis on Raman spectroscopy under high pressure conditions on 1D and 2D systems. He spent two years (2016–2017 and 2018–2019) at the Federal university of Ceará as a Postdoctoral Fellow, working with high pressure Raman spectroscopy on 1D carbonaceous materials and one year (2017–2018) at the Federal university of Minas Gerais working with TERS applied on 2D systems.
