2D Semiconductor Materials

Interest in 2D materials has increased dramatically since the successful mechanical exfoliation of graphene in 2004 by Novoselov and Geim. Many other materials which also consist of atomically thin layers weakly bonded to one another by van de Waals forces have now also been studied in their 2D form.

2D materials can broadly be grouped by their properties and potential applications. 2D semiconductors have highly desirable properties for optoelectronics and nanotechnology. Graphene and other 2D materials (such as phosphorene and Molybdenum Disulfide) have emerged as promising candidates for transparent and flexible electrodes, electrochemical capacitor devices for energy storage, and anti-corrosion coatings. There is also a potential use for graphene and 2D materials in biomedical applications such as tissue engineering, sensors and drug deliveries, and aerospace applications. Due to its extraordinary properties and relatively low cost, graphene and its derivatives have opened the window of opportunity for researchers to develop materials and devices with novel functionalities, and to improve the quality of existing products. While comparatively few established 2D materials exhibit magnetic properties, new research is drawing more interest to this area too. One of the most studied magnetic 2D materials is iron phosphorus trisulfide (FePS3). In reference to what is undoubtedly the most famous 2D material, it is commonly referred to as 'magnetic graphene'.

2D materials can be created from a bulk material via several different methods, the simplest of which is mechanical exfoliation. Also known as the Scotch-tape method, the weak weakly van der Waals forces that bond the single-atom-thick layers in the material together can be overcome with a piece of sticky tape. More sophisticated methods like chemical vapour deposition can be used for larger and more uniform 2D flakes.
