| Popis: | Barium intercalation into InSe and GaSe layered crystals has been demonstrated by electron probe X-ray microanalysis. The transmission and photoconductivity spectra of BaxInSe (0 < x ≤ 1) show an additional peak and a shift of the intrinsic edge. The energy position of the main exciton maximum and the width of the lowest exciton band in BaxGaSe are found to be nonmonotonic functions of Ba content. |
