Description

**teMatDb** is a digitized thermoelectric material database constructed from literature-reported thermoelectric property curves. This release (v1.1.6) serves as the foundational dataset (*teMatDb272*) used in the teMatDb-based paper currently in preparation.

The dataset includes:

- 355 raw digitized thermoelectric property (TEP) curve sets  
- 272 high-fidelity samples curated using a self-consistent ZT filtering protocol  
- Temperature-dependent curves for:  
  - Seebeck coefficient, α(T)  
  - Electrical resistivity, ρ(T)  
  - Thermal conductivity, κ(T)  
  - Figure of merit, ZT(T)

This database supports reproducible thermoelectric analysis and data-driven materials research.
