Interface engineering is a research area that focuses on designing and optimizing the interface between different materials or components in order to enhance their performance and functionality. This can involve manipulating the physical, chemical, or electronic properties of the interface to improve adhesion, conductivity, thermal stability, or other characteristics. Interface engineering is commonly applied in fields such as materials science, nanotechnology, and electronics to develop new materials, devices, and systems with improved properties and functionality. Researchers in this area often use a combination of experimental and theoretical methods to study and manipulate the interfaces between materials at the atomic or molecular level.
