Description
Mesude Zeliha Arkan, PhD, Emre Arkan, PhD
The energetic performance of materials is strongly influenced by their surface properties and chemical composition. Key surface characteristics—roughness, functionalization, and charge distribution—govern interfacial interactions, charge-transfer efficiency, and energy dissipation, particularly in materials used for energy harvesting, storage, and conversion. Increased surface roughness can enlarge the contact area in triboelectric systems, enhancing charge generation, while specific functional groups modify the work function and electron affinity. At the compositional level, dopants, nanofillers, and tailored molecular structures can adjust the dielectric constant, electrical conductivity, and polarization behavior, all of which are critical for optimizing energy performance. This lecture will address these aspects through the following topics:
-Fundamentals of surface and interface properties
-Surface treatment methods
-Techniques for measuring surface properties
-Electrical properties influenced by surface engineering
