In this pedagogical talk we would like to discuss the basic science behind nanoscience and nanotechnology suitable for the yound mind. Several examples from nature as well as from basic science will be illustrated. The role of basic quantum mechanics will be highlighted. In the second part, we would like discuss the intriguing physics of two dimensional (2D) materials. Dirac materials are a class of complex and functional nanomaterials offering great potential in the development of new electronic components. A tight binding (TB) model along with density functional theory (DFT) will be used to unravel the characteristic features of Dirac points in these systems.
Update Study Group (erstwhile ‘Update’) began publication from Kolkata, India in 1999. From the very beginning, ‘Update’ stood for international socialist movement and Marxist world outlook. ।
