Photo-sensing devices based on two-dimensional (2D) materials are compared to conventional designs and their respective differences discussed in detail. A range of 2D materials are introduced with a generic comparison based on their individual properties and importance to the generation of a photoresponse. Besides transition-metal dichalcogenides, the chapter also deals with black phosphorous photosensor devices. Different heterostructure architectures based on 2D layered structures are investigated and their role in next generation optoelectronics is discussed.1 aLate, Dattatray, J.1 aBhat, Anha1 aRout, Chandra, Sekhar  uhttps://library.ncl.res.in/content/photo-sensor-based-2d-materials
