Figure 2. Change in thermoelectromotive force (Seebeck coefficient) with addition of Sb impurity to SnSe

Caption

SnSe starts out with p-type conduction at low Sb concentrations (<0.5%), changes to n-type at intermediate concentrations (0.5%<x<5%), and switches back to p-type at high concentrations (x>0.5%).
