Surface science

Surface science is the study of physical and chemical phenomena that occur at the interface of two phases, including solidliquid interfaces, solid–gas interfaces, solid–vacuum interfaces, and liquidgas interfaces. It includes the fields of surface chemistry and surface physics.[1] Some related practical applications are classed as surface engineering. The science encompasses concepts such as heterogeneous catalysis, semiconductor device fabrication, fuel cells, self-assembled monolayers, and adhesives. Surface science is closely related to interface and colloid science.[2] Interfacial chemistry and physics are common subjects for both. The methods are different. In addition, interface and colloid science studies macroscopic phenomena that occur in heterogeneous systems due to peculiarities of interfaces.
