Interfacial dipoles arise at the interface between two different materials, primarily due to differences in electronic structure and potential. They significantly influence electronic properties like charge injection and energy level alignment, which are crucial for the performance of electronic devices such as organic light-emitting diodes and solar cells.

Difference in electronic structure

Potential refers to the inherent capacity or ability within an object, system, or individual to develop, achieve, or bring about a particular outcome or effect. It is often used in various fields to describe latent qualities or possibilities that can be realized under certain conditions or through specific actions.

Electronic properties refer to the behavior and characteristics of electrons in materials, which determine a material's electrical conductivity, band structure, and other related phenomena. Understanding these properties is crucial for the development of electronic devices and materials science innovations.
