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 of incorporated 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.

(en) 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 1,06 na 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. (cs)
