Abstract

In this project, we looked into the electronic and structural properties to find the best value for adding K atoms to a SiNR substrate by adsorption on the surface of a clean material. Special positions considered are peak, valley, bridge, and hollow to place K atoms with Si-Si bond lengths from 2.5 Å to 3.0 Å and choose the hollow position corresponding to the long bond. As a result, 2.29 Å reaches the optimum with the lowest energy of 1.66 eV; the magnetic moment has a value of 0.39 µB and has the most stable structure compared to other positions. Compound products produced after doping have a very diverse range of prohibitions, suitable for creating new-generation electronic systems or spin devices.
