“…Teir band structure is near the lead chalcogenides, not the alkali halides, as they have two more s-valence-electrons than the band structure of the flled shell of the rare gases. Tey are expected to work above room temperature due to their high atomic numbers (Br: 35 and Tl: 81) and high density (7.56gm/cm 3 ) [5][6][7][8][9][10].…”

This work studies the thallium halogenide TlBr/BrCl quantum dot (QD) semiconductor structure and specifies its optical properties. This QD structure is poorly studied. High gain is obtained, with two peaks at 800 and 3000 n m . Doping is shown to increase the gain by one order. Then, TlBr QD semiconductor optical amplifier (SOA) characteristics are studied. High dB gain is shown mainly at the doped structure, which can be used in various inline applications.
