Data for Piezoelectric and pyroelectric effects induced by interface polar symmetry

The built-in electric field in the depletion region induces polar structures in the semiconductors and generates substantial piezoelectric and pyroelectric effects. In particular, the pyroelectric coefficient and figure of merit of the interface are over one order of magnitude larger than those of conventional bulk polar materials. Our study enriches the functionalities of heterostructure interfaces, offering a distinctive approach to realizing energy transduction beyond the conventional limitation imposed by intrinsic symmetry.<br><br>Data record consists of an excel spreadsheet, organised internally according to corresponding figure, containing the raw data used in the associated publication.

Columns within the sheets are labelled with both variable and unit of measurement. Further details on the data are contained within the excel file.
