This thesis is an effort to understand electronic structure and optical properties of low-dimensional conjugated molecules such as polyatomic aromatic hydrocarbons and nanoribbons composed of perylene monomers in addition ...

Elements in the periodic table are categorized into four major blocks, main group (MG) elements, transition metals (TM), lanthanides (Ln), and actinides (An), which differ dramatically. Recent studies revealed some interesting ...

To mitigate the adverse environmental effects of burning fossil fuels, it became necessary to explore alternative ‘clean’ renewable energy sources to meet the ever-increasing energy demands. While silicon-based solar cell ...
