The optical absorption of Dirac fermions in silicene, subjected to a perpendicular magnetic field, is study by the perturbation theory. Analytical expression of the absorption coefficient is obtained taking account the electron - impurity interaction at very low temperatures. Absorption spectra show the appearance of cyclotron-impurity resonant peaks. The dependences of the absorption coefficient on the magnetic field and temperature are also obtained and discussed.

Presenter: Le Thi Thu Phuong
