Two dimensional 2d materials. Two dimensional 2d materials sometimes referred to as single layer materials are crystalline materials consisting of a single layer of atoms. 10 9 m but yet exhibit great performance in various applications from digital analog devices optoelectronics to flexible electronics and biotechnology. Two dimensional materials such as graphene have many advantages over bulk three dimensional 3d materials from both scientific and technological perspectives 6 83. These materials have found use in applications such as photovoltaics semiconductors electrodes and water purification.
The optical properties of 2d materials are quite different from those of bulk 3d materials which results in significantly different plasmon dispersion relationships 6 127 6 128. 2d materials can generally be categorised as either 2d allotropes of various elements or as compounds consisting of two or more. Two dimensional materials have attracted much interest in recent years owing to their chemical and optical properties. Nus researchers have created a whole new library of atomically thin two dimensional 2d materials christened ic 2d to denote a class of materials based on self intercalation of native atoms into the gap between the layers of crystals.
In two dimensional 2d materials two dimensions are outside the nanoscale and one dimension is only a single or few atomic layers thick. 2d materials two dimensional 2d materials are only a few atoms thick approx. This class exhibits plate like shapes and includes graphene and other monolayer materials such as transition metal dichalcogenides black phosphorous phosphorene and diatomic hexagonal boron nitride.
