Effect of temperature variation on shift and broadening of exciton band in Cs₃Bi₂I₉ layered crystals
The exciton reflection spectra of Cs₃Bi₂I₉ layered crystals is investigated in the temperature region 4.2–300 K with light polarization E ⊥ c. It is estimated that the energy gap Eg equals 2.857 eV (T = 4.2 K) and the exciton binding energy Ry is 279 meV. A nontraditional temperature shift of...
