My research work involves the quantum mechanical study of Diamondoids. Diamondoids are nanocaged diamond with hydrogen termination. We modify these diamondoids by means of doping and functionalization. We investigate the stability of these modified diamondoids and probe the electronic structure of these molecules under the framework of  Density Functional Theory (DFT) using SIESTA. We also study the carbene based self-assembled monolayers (SAMs) of diamondoids on various metal substrates and investigate their mechanical and electronic properties using VASP. The bonding characteristics  and the adsorption properties of these SAMs  are investigated as well as the morphology of the modified surfaces. Furthermore, in view of their nanotechnological applications we probe  the emission properties of these modified diamondoids using GAMESS and ORCA.

My research work involves the quantum mechanical study of Diamondoids. Diamondoids are nanocaged diamond with hydrogen termination. We modify these diamondoids by means of doping and functionalization. We investigate the stability of these modified diamondoids and probe their electronic structure under the framework of Density Functional Theory (DFT) using SIESTA. We also study the carbene based self-assembled monolayers (SAMs) of diamondoids on various metal substrates and investigate their mechanical and electronic properties using VASP. The bonding characteristics and the adsorption properties of these SAMs are investigated as well as the morphology of the modified surfaces. Furthermore, in view of their nanotechnological applications we probe the emission properties of these modified diamondoids using GAMESS and ORCA.
