Two-dimensional materials (2D materials) are known as those whose thickness can be reduced to a few layers of atoms or even a single one by very simple methods, for example, by separating those layers with common adhesive tape. Graphene was the first 2D material that was isolated in 2005 and dozens of 2D materials with different properties have been discovered ever since. One of them is FePS3, the material studied in the article published today in the journal npj 2D Materials & Applications, led by researchers from the University of Alicante Department of Applied Physics and the Institute of Materials (IUMA).
UA Distinguished Researcher Reyes Calvo and postdoctoral researcher María Ramos are the main authors of the article Ultra-broad spectral photo-response in FePS3 air-stable devices where they collaborate with experts in this field from the Madrid Science Institute (ICMM-CSIC) and the University Molecular Science Institute (ICMol). The article is the result of research into the photoelectric properties of this new two-dimensional material, which may be a good candidate for optoelectronic applications due to its broad photosensitive response, according to Reyes Calvo. The material can detect light in a wide range of the optical spectrum, from infrared to ultraviolet, which is a first step towards its potential application in photodetection, as the researcher pointed out.
Made up of iron, phosphate and sulphur, FePS3 is an affordable material that can be very easily reduced to a few layers of atomic thickness, as Calvo explained, who, together with María Ramos, is going to continue with this research aimed at revealing another of its characteristics: magnetism. When FePS3 cools down, it is a magnetic material, which could be used in other applications, such as those related to spintronics, as the researcher stated. Spintronics is an emerging technology that will enable the production of increasingly smaller and more efficient microelectronic devices, based on the magnetic properties of electrons (spin).
