“…Silicene, regarded as the 'silicon version of graphene,' also has a hexagonal structure [117][118][119]. Silicene is the single-layer version of graphene, having the constituent Si atoms arranged in a hexagonal form via covalent bonds [22,23]. Silicene shares many properties of graphene, like zero bandgap, high mobility of carriers and the presence of a Dirac cone in its band structure.…”

“…TMDCs detect light at different wavelengths because of layer dependent bandgap [19][20][21]. Most of the TMDCs have a direct Photo-Detectors Based on Two Dimensional Materials DOI: http://dx.doi.org/10.5772/intechopen.95559 nature of the bandgap, limiting the phonon scattering in TMDCs photodetectors, which leads to better efficiency [22]. 2D materials have localized electronic bands, leading to sharp peaks in the density of states (DOS) called Van Hove singularities at specific energies [22].…”

“…Generally, in 2D materials like TMDCs, these singularities reside near conduction and valence bands. This leads to an increased probability of electron-hole pair generation upon excitation with light [22,23]. TMDCs photodetectors show excellent light to current conversion with high responsivity [22].…”

2D materials like transition metal dichalcogenides, black phosphorous, silicene, graphene are at the forefront of being the most potent 2D materials for optoelectronic applications because of their exceptional properties. Several application-specific photodetectors based on 2D materials have been designed and manufactured due to a wide range and layer-dependent bandgaps. Different 2D materials stacked together give rise to many surprising electronic and optoelectronic phenomena of the junctions based on 2D materials. This has resulted in a lot of popularity of 2D heterostructures as compared to the original 2D materials. This chapter presents the progress of optoelectronic devices (photodetectors) based on 2D materials and their heterostructures.

Polarization‐sensitive photodetectors are gaining numerous attention since polarization detection is important in geological remote sensing, atmospheric monitoring, military recon, and medical examination. Among various reported photoactive materials for photodetectors, metal halide perovskites have outstanding advantages such as tunable band gaps, excellent optoelectronic properties, and easy fabrication. Moreover, the characteristics of crystal structure anisotropy and controllable growth orientation of perovskite crystals endow the perovskite photodetector with the ability to identify light polarization states. This review outlines the recent research progress of perovskite photodetectors on polarization‐sensitive detection. Firstly, key device parameters of polarization‐sensitive detection are introduced. Then, the recent progress of polarization‐sensitive perovskite detectors in the field of linear and circular polarization is reviewed according to the different principles of polarization response. Finally, the challenges of polarization‐sensitive perovskite photodetector are discussed.
