Interference of resonance luminescence of exciton polaritons in CuGaS2 crystals
The nonmodulated and wavelength-modulated reflection spectra of CuGaS2 crystals for the polarization Е||c of 10 K are studied. The states n = 1, 2 and 3 of the excitons Γ4 (A-excitons) and n = 1, n = 2 of B- and C-excitons are found. The nonmodulated absorption spectra for the polarization E⊥c at...

| description |
The nonmodulated and wavelength-modulated reflection spectra of CuGaS2 crystals for
the polarization Е||c of 10 K are studied. The states n = 1, 2 and 3 of the excitons Γ4 (A-excitons) and n = 1, n = 2 of B- and C-excitons are found. The nonmodulated absorption spectra
for the polarization E⊥c at 10 K have been studied. The states n=1, 2 and 3 of Γ5 excitons are
found. The main parameters of the A (Γ4, Γ5 ) and B, C exciton series at the energies of the
longitudinal and transverse excitons Γ4 for the states n = 1 and n = 2, the effective masses of
electrons ( m*e
1) and holes (m*
v1, m*
v2 , m*
v3) are determined. |
