These atoms are more likely to form bonds with other atoms without the need for external influence or energy. Is the formation of a bond between two isolated atoms a spontaneous process? No, the formation of a bond between two isolated atoms is not a spontaneous process. It requires a ...
In addition, 2D materials doped with than two or more kinds of heteroatoms are also attracted much attention [56,57]. Fig. 2h shows another important defects in 2D materials, the edge sites [2]. The unsaturated atoms at edges will produce remarkable differences in electronic features and ...
One possible approach is the introduction of a hybrid model that combines the extrinsic representation (the UM) with more intrinsic factors, such as the presence of relativistic jets, outflows, or evolutionary processes. Jets can significantly alter the spectral characteristics of the source, ...
