Bridging the Physics and Chemistry of graphene. From Huckel aromaticity to Dirac cones and topological insulators
Aristides D. Zdetsis
By bridging graphene and benzene through a well-defined sequence of polycyclic aromatic hydrocarbons and their inherent shell structure, J. Phys. Chem. C, 2018, 122, 17526, it is s…
Systematic spatial and stoichiometric screening towards understanding the surface of ultrasmall oxygenated silicon nanocrystal
Shanawer Niaz, Aristides D. Zdetsis, Emmanuel N. Koukaras +2
In most of the realistic ab initio and model calculations which have appeared on the emission of light from Si nanocrystals, the role of surface oxygen has been usually ignored, un…
A Comprehensive Ab Initio Study of Electronic, Optical and Cohesive Properties of Silicon Quantum Dots of Various Morphologies and Sizes up to Infinity
Shanawer Niaz, Aristides D. Zdetsis
We present a comprehensive and integrated model-independent ab initio study of the structural, cohesive, electronic, and optical properties of silicon quantum dots of various morph…
Optical Properties of Pure and Mixed Germanium and Silicon Quantum Dots
Shanawer Niaz, Aristides D. Zdetsis, Manzoor Ahmad Badar +3
We study the optical properties of hydrogen passivated silicon, germanium and mixed Ge/Si core/shell quantum dots (QDs) using high accuracy Density Functional Theory (DFT) and time…
