2D‐Pyroelectric Materials for Waste Thermal Energy Harvesting and Beyond
Advanced Energy MaterialsPolar 2D materials hold the emerging functionalities such as ferro‐, piezo‐, and pyro‐electric properties. On account of infrared‐active low bandgap and polar nature at reduced dimensionality, they served as an ideal choice of pyroelectric material.

Second-order nonlinear optical polymers must be poled in order to achieve the required non-centrosymmetry. Periodically poled materials are required for phase-matched operation of polarization converters1 and parametric devices2. For second-harmonic generation with modes of different order1, three-dimensionally (3-D) poled patterns are needed to ...

Pyroelectric Thermal Imaging Devices
IEEE Transactions on Sonics and Ultrasonics, 1972Study of the pyroelectric properties of a number of ferroelectric materials has shown that they can be used as sensitive infrared detectors suitable for use in thermal imaging systems. In particular when single domain triglycine sulphate elements of adequate quality are used, the detectivity obtained approaches within an order of magnitude of an ideal ...
