Interface physics is a research field dedicated to investigating the unique physical phenomena occurring at the boundaries, or interfaces, between different materials, phases, or systems. It examines how the properties and interactions of matter are profoundly modified in these interfacial regions compared to the bulk, encompassing structural, electronic, thermal, and dynamic processes critical for diverse phenomena like adhesion, catalysis, and charge transport. This interdisciplinary area plays a vital role in understanding and engineering advanced materials and devices across numerous scientific and technological domains.
