Dependence of Solidification for Bi2Te3−xSex Alloys on Their Liquid States

Scientific Reports, 2017
The resistivity versus temperature (ρ-T) behaviours of liquid n-type Bi2Te3−x Se x (x = 0.3, 0.45 and 0.6) alloys are explored up to 1050 °C. A clear hump is observed on all ρ-T curves of the three studied Bi2Te3−x Se x melts during the heating process ...
