    Point and structural defects in Bi2PbxTe3 single crystals

  • Original language description

    The study of the doping process of Bi2Te3 by Pb atoms in wide range of lead concentration ((1.0-80.0)x10 18 cm-3) revealed two distinct areas of influence of incorporated Pb atoms on changes in free carrier concentration. While at lower concentration ofincorporated Pb (up to 20x10 18 cm-3 at. Pb cm-3) the ratio of generated holes to one incorporated Pb atom falls from value of 1.06 down to 0.55, at higher concentration ((20-80)x10 18 Pb at. cm-3) the value stays constant. The observed behaviour of seeming electrical inactivity of the incorporated Pb atoms is explained by a point defect model taking into account the interaction between the entering Pb atoms and native lattice defects of Bi2Te3 crystal structure.

    Bodové a stukturní poruchy v monokrystalech Bi2PbxTe3

  • Czech description

    Studium procesu dotace monokrystalů Bi2Te3 atomy olova prokázalo dvě oblasti rozdílného vlivu atomů olova na změnu koncentrace volných nositelů proudu. Pro koncentraci olova (1-20)x10 18 cm-3 klesá poměr počtu generovaných děr na jeden atom olova z 1,06na 0,55. Pro koncentraci olova (20x80)x10 18 cm-3 je poměr konstantní. Tato pozorovaná zdánlivá elektrická neaktivita zabudovaných atomů olova je vysvětlena jejich interakcí s přirozenými poruchami mřížky v monokrystalech Bi2Te3.
