Abstract

RRUFF database is proposing the Raman spectra of two molybdenum disulfide MoS_2 samples. Here we show the q-BWF fitted functions to the E_2g and A_1g Raman bands of these samples. The q-BWF functions are generalizing the Breit-Wigner-Fano line shape in the framework of the q-exponential function proposed by Constantino Tsallis and his statistics. The fitted q-BWF functions to pyramid and monolayer Raman spectra by Fabbri et al., 2022, are also proposed. Some review of Raman spectroscopy of MoS_2 is proposed too.
