A High-Quality Thermoelectric Material Database with Self-Consistent ZT Filtering
Byungki Ryu, Ji Hui Son, Sungjin Park +5
This study presents a curated thermoelectric material database, teMatDb, constructed by digitizing literature-reported data. It includes temperature-dependent thermoelectric proper…
Asymmetric Electronic Band Alignment and Potentially Enhanced Thermoelectric Properties in Phase-Separated Mg2X (X=Si,Ge,Sn) Alloys
Byungki Ryu, Samuel Foster, Eun-Ae Choi +8
The Mg2X (X=Si, Ge, Sn) based alloy is an eco-friendly thermoelectric material for mid-temperature applications. The Mg2Si1-xSnx and Mg2Ge1-xSnx alloys can be phase-separated into…
Reference compositions for bismuth telluride thermoelectric materials for low-temperature power generation
Nirma Kumari, Jaywan Chung, Seunghyun Oh +5
Thermoelectric (TE) technology enables direct heat-to-electricity conversion and is gaining attention as a clean, fuel-saving, and carbon-neutral solution for industrial, automotiv…
Wiedemann-Franz Law and Thermoelectric Inequalities: Effective ZT and Single-leg Efficiency Overestimation
Byungki Ryu, Seunghyun Oh, Wabi Demeke +6
We derive a thermoelectric inequality in thermoelectric conversion between the material figure of merit (ZT) and the module effective ZT using the Constant Seebeck-coefficient Appr…
Thermoelectric Algebra Made Simple for Thermoelectric Generator Module Performance Prediction under Constant Seebeck-Coefficient Approximation
Byungki Ryu, Jaywan Chung, SuDong Park
While thermoelectric material performances can be estimated using the ZT, predicting the performance of thermoelectric generator modules (TGMs) is complex due to the non-linearity…
