Off-centered Pb interstitials in PbTe

Sungjin Park, Jongho Park, Byungki Ryu +1

In this work, we calculate the defect properties of low-symmetry Pb interstitials in PbTe using first-principles density-functional theory calculations. We break the symmetry impos…

Native point defects and low $p$ -doping efficiency in $M g_{2} (S i, S n)$ solid solutions: A hybrid-density functional study

Byungki Ryu, Eun-Ae Choi, Sungjin Park +5

We perform hybrid-density functional calculations to investigate the charged defect formation energy of native point defects in $M g_{2} S i$ , $M g_{2} S n$ , and their solid solutions. The…

Counterintuitive example on relation between ZT and thermoelectric efficiency

Byungki Ryu, Jaywan Chung, Eun-Ae Choi +3

The thermoelectric figure of merit ZT, which is defined using electrical conductivity, Seebeck coefficient, thermal conductivity, and absolute temperature T, has been widely used a…
