The objective of this study is to investigate the influence of external factors, such as boundary conditions, on the phonon-induced thermodynamic properties of quasi-two-dimensional nanostructures (ultrathin films and superlattices), with the ultimate goal of approaching high-temperature superconductivity. The method for achieving this goal is based on engineering a phonon energy gap, also known as “phononica” or “nanophononics,” which can significantly affect the thermodynamic and other physical properties of a material, particularly its thermal capacity and thermal conductivity. Recent research suggests that engineering these properties can influence superconducting behavior. By tuning the phonon energy gap in nanostructures, it is possible to significantly influence their thermodynamic properties and potentially enhance superconducting performance, with implications for energy efficiency and power consumption.
