Abstract

A complete understanding of transitions to superconducting phases in materials is crucial for the development of versatile technological applications. Recent research has revealed that electronic doping of copper oxides in one-dimensional structures can induce superconducting phases across a wide range of system parameters. Inspired by these findings, in this study, we investigate how doping of one-dimensional organic salts can enhance the superconducting properties of these compounds. We will employ the extended Hubbard model, which effectively describes the electronic behavior in these systems, considering Coulomb interactions between electrons in a one-dimensional lattice. Our goal is to understand the impacts of electronic doping on improving superconducting phases in low-dimensional systems, offering insights for the fields of Chemistry, Physics, and Materials Science.
