“…[91] For operation in the longwave infrared region, with a 332 nm wide spectra band, John et al combined a pyroelectric AlN film with a plasmonic Au array of fine-scale holes to achieve 95% absorption and 18.9 dB of spectral selectivity. [96] For far-infrared detectors at THz wavelengths beyond 20 μm, Arose et al investigated the factors that affected the design of a photodetector using simulations based on a plasmonic metal film with a periodic array of subwavelengths that was deposited on the surface of a range of pyroelectric materials, which included bulk LiTaO 3 and AlN films. [95] In addition, a number of detectors have been reported that are based on pyroelectric ZnO, which is attractive in this context since it can be readily formed in thin film, nanoparticle, or nanowire form.…”

With the growing global energy crisis, research into new energy materials that can potentially transfer heat into electricity has become a worldwide imperative. Pyroelectric materials are polar materials that are able to produce electrical charge in response to temperature change. These materials are of interest for infrared sensing, energy harvesting, and emerging applications in chemistry and biology. However, unlocking their potential requires the temperature changes to be both large and rapid. To achieve this goal, pyroelectric materials can be used in synergy with plasmonic nanomaterials, which provide highly localized and rapid heating upon illumination at the plasmonic resonances. Plasmonic‐pyroelectric combinations are therefore being used for a variety of electrical, thermal, electrochemical, and biological studies and are inspiring new technological applications. In this review, the underlying mechanisms of the pyroelectric and plasmonic effects are introduced and the benefits of combining them are outlined. A range of applications is then overviewed. Critical challenges and future perspectives to further develop the underlying science of these systems and to create highly efficient plasmonic‐pyroelectric materials and structures are discussed.

“…A polycrystalline material consists of a disordered network of small, highly organized crystal lattices. This can be commonly found in films deposited using physical deposition techniques like high temperature reactive sputtering [45]. The amorphous materials have no long range ordering of atoms; most solution-processable materials fall into the amorphous category.…”

This review is written to introduce infrared photon detectors based on solution-processable semiconductors. A new generation of solution-processable photon detectors have been reported in the past few decades based on colloidal quantum dots, two-dimensional materials, organics semiconductors, and perovskites. These materials offer sensitivity within the infrared spectral regions and the advantages of ease of fabrication at low temperature, tunable materials properties, mechanical flexibility, scalability to large areas, and compatibility with monolithic integration, rendering them as promising alternatives for infrared sensing when compared to vacuum-processed counterparts that require rigorous lattice matching during integration. This work focuses on infrared detection using disordered semiconductors so as to articulate how the inherent device physics and behaviors are different from conventional crystalline semiconductors. The performance of each material family is summarized in tables, and device designs unique to solution-processed materials, including narrowband photodetectors and pixel-less up-conversion imagers, are highlighted in application prototypes distinct from conventional infrared cameras. We share our perspectives in examining open challenges for the development of solution-processable infrared detectors and comment on recent research directions in our community to leverage the advantages of solutionprocessable materials and advance their implementation in next-generation infrared sensing and imaging applications.among many other areas. Commercially available IR detectors are predominantly based on vacuum-processed inorganic compound semiconductors, which are structurally rigid, brittle, and require fabrication via complex epitaxial growth and costly processes. A new generation of solution-processable semiconductors have been reported in the past few decades including colloidal quantum dots (CQDs) [1,8,9], organic semiconductors (OSCs) [4,7,10,11], perovskites [1,12,13], and two-dimensional (2D) materials [5,14]. These materials offer sensitivity within the IR spectral regions and the advantages of ease of fabrication

Plasmonic metasurfaces based on ensembles of distributed metallic nanostructures can absorb, scatter and in other ways shape light at the nanoscale. Forming hybrid plasmonic metasurfaces by combination with other materials opens up for new research directions and novel applications. This perspective highlights some of the recent advancements in this vibrant research field. Particular emphasis is put on hybrid plasmonic metasurfaces comprising organic materials and on concepts related to switchable surfaces, light-to-heat conversion, and hybridized light-matter states based on strong coupling.
