An atom of boron (atomic number 5) contains five electrons. The n = 1 shell is filled with two electrons and three electrons will occupy the n = 2 shell. Because any s subshell can contain only two electrons, the fifth electron must occupy the next energy level, which wi...

While atomic resolution is routinely achieved for metal supported thin oxide films using scanning tunnelling microscopy (STM), most studies have focused on relatively idealised films and the structure of GBs has not been resolved11–13. On the other hand, the structure of GBs in bicrystals has ...
room temperature. After a brief introduction to nanoribbon nomenclature, experimental synthesis, and characterization, this chapter guides through the theoretical toolbox available for modeling their electronic structure, starting from simple empirical models and ending with state-of-the-art ab initio ...
The electronic structure of hydrogenated h-BN nanoflakes depends on the edge atom species and their flake size. The energy gap between the lowest unoccupied (LU) and the highest occupied (HO) states of the nanoflakes with N edges is narrower than that of the nanoflakes with B edges and the...
