Theoretical Exploration of Electronic, Magnetic, and Thermodynamic Attributes of a Penta-Graphene Structure Under Strain and Electric Field via Tight-Binding Study

Penta-graphene (PG) structures have enticed enormous appeal due to their exotic physical properties. Based on tight-binding (TB) calculations, we demonstrated that the band gap of the PG monolayer can be controlled by applying external factors such as an electric field, magnetic field (MF), and strain. This ability to manipulate the electronic properties makes PG monolayers highly practical for electronic applications. Here, for the first time, we study the impact of the electric field, MF, and strain on the electronic heat capacity (EHC) and Puali magnetic susceptibility (PMS) properties of the PG monolayer using the TB method and the Green function technique. Our results showed that the PG monolayer is a paramagnetic material. Applying strain, electric field, and MF reduces the PMS of the PG structure. Thus, the EHC increases with the application of an electric field and compression strain. Overall, controlling PMS and EHC in PG monolayers opens up opportunities for advancements in spintronic, energy storage, thermal management, sensing, and nanoelectronics, leading to advanced technologies in several industries.
