A database of only superlattice structures used in thermoelectric studies made of oxides, III-V, chalcogenides, group IV superlattice, V-VI, etc. The objective is to extract thermoelectric parameters, to see if the work is theoretical or experimental in order to see the enhancement in power factor through seebeck coefficient and thermal conductivity. include if the measuremnts are done in cross plane or in plane. Type: for review paper

Data Verification Status Taxonomy
To maintain rigorous scientific standards, Sci-database differentiates between automated signals and human audit:
Value located and extracted from the full-text PDF by the Kateeb engine.
An independent second model produced a compatible value during automated second-pass review.
A named researcher audited the value against the visual page coordinates.
Performance evaluated against a standardized, published evaluation protocol.
An independent external research group reproduced the extraction and experimental result.
