Researchers from Institute of Nano Science and Technology (INST), Mohali an autonomous institute under the Department of Science < Technology, have made computer based designs of nano-materials with superhigh piezoelectricity which can be the building blocks of futuristic nano-electronics for applications like ultrathin, next-generation nano-transistors.
Piezoelectricity is the generation of electricity in certain materials upon application of pressure. Its applications have eased our daily lives through the use of lighters, pressure gauge, sensors and so on.
Piezoelectricity in 2D materials was first predicted theoretically in 2012 and later observed and confirmed experimentally in monolayer in 2014. Since then, there has been a surge in research interests in piezoelectricity in graphene-like two-dimensional (2D) materials, thereby leading to the exploration of piezoelectricity in 2D materials or avenues to induce or enhance piezoelectricity in 2D materials. However, most of the 2D materials reported till date mainly show in-plane piezoelectricity; however, for device-based applications, out-of-plane piezoelectricity is very much desired and sought after.
