The radiation damage produced by 10 keV protons implanted in CuInSe 2 single crystal with a dose of 3x10 16 cm -2 has been studied by Rutherford backscattering-channelling [25]. The experimentally estimated concentration of atoms in the indium sub-lattice displaced to interstitial positions was found to be less than 20% of that predicted by TRIM one suggesting that more than 80% of primary defects are healed during or shortly after the implantation.…”

CuInSe 2 contains both donors and acceptors showing p-type conductivity if the concentration of acceptors is higher than that of donors.…”

Landau levels of the C-exciton in CuInSe2 studied by magneto-transmission

“…Early optical spectroscopy studies of the excitonic properties of CuInSe 2 revealed the complexity of the valence band, which is split into A, B, and C sub-bands by the simultaneous influence of the non-cubic crystal field and spin-orbit coupling. 5 Recently, the excitonic studies were extended by works based on new advances in the material structural quality [6][7][8][9] determining accurate values of the A and B exciton binding energies E b 7 and hole effective masses. 9 Significantly fewer papers however are concerned with the C exciton, although the C-band parameters are necessary for the development of kp theory in the chalcopyrites.…”
