Improving the <i>ZT</i> of SnTe using electronic structure engineering: unusual behavior of Bi dopant in the presence of Pb as a co-dopant
U. Sandhya Shenoy, D. Krishna Bhat
Abstract
Extraordinary tuning of electronic structure of SnTe by Bi in the presence of Pb as a co-adjuvant dopant. Synergistic effect of resonance level, increase in the band gap, valence and conduction sub-bands convergence leads to enhanced TE performance.
