Diamond has a natural unstrained state with an ultrawide electronic bandgap of 5.6 eV, meaning that it is a strong electrical insulator inside which electrons do not move through readily (Shi et al., 2020). Doping can improve the conductivity of diamond, with boron doped diamond a common ...
(3.37 × 10−8cm) is sufficiently large to preclude localized bonding between the layers; the bonding between layers is probably byvan der Waalsinteraction (i.e., the result of attraction betweenelectronsof one carbon atom and the nuclei of neighbouring atoms). Ready cleavage, as compared ...
A type of chemical reaction in which one substance (an oxidizing agent) accepts electrons from another substance (a reducing agent) and is thereby reduced (while the reducing agent is oxidized) is frequently observed with carbon and its compounds. Although carbon is usually a reducing agent, unde...

In a nitrogen-doped graphene layer, pyridinic N and pyrrolic N donate one and two electrons, respectively, to the π-system of the carbon to give the carbon network a partially negative charge, which enhances the electrochemical activity for Na and K-storage. However, in these two structures ...
Because of this practical limitation, core electrons made by frozen and the basis set used is the 3-21G, for the geometry optimization. The Density Functional Theory (DFT) was extensively used in the calculation of the many properties due to the considerable decrease of the computational efforts...
