Surface chemistry Surface chemistry An absorption isotherm is an analytical method for estimating the surface physical and chemical values of materials. ...more on Wikipedia about "Absorption isotherm"
(Adatoms) An adatom is simply an adsorbed atom. This term is generally used in surface chemistry, when describing the adsorption of atoms to surfaces. ...more on Wikipedia about "Adatoms"
The electrical double layer describes the variation of electric potential near a surface, and has a large bearing on the behaviour of colloids and other surfaces in contact with solutions. The analogue in a plasma is the double layer. ...more on Wikipedia about "Electrical double layer"
Kelvin probe force microscopy (KPFM), also known as surface potential microscopy, is a noncontact variant of atomic force microscopy (AFM) that was invented in 1991. With KPFM, the work function of surfaces can be observed at atomic or molecular scales. The work function relates to many surface phenomena, including catalytic activity, reconstruction of surfaces, doping and band-bending of semiconductors, charge trapping in dielectrics and corrosion. The map of the work function produced by KPFM gives information about the composition and electronic state of the local structures on the surface of a solid. ...more on Wikipedia about "Kelvin probe force microscope"
The Langmuir equation or Langmuir isotherm or Langmuir adsorbtion equation relates the coverage or adsorbtion of molecules on a solid surface to gas pressure or concentration of a medium above the solid surface at a fixed temperature. The equation was developed by Irving Langmuir in 1916. The equation is stated as: ...more on Wikipedia about "Langmuir equation"

NEXAFS (Near Edge X-ray Absorption Fine Structure) is an element-specific electron spectroscopic technique which is highly sensitive to bond angles, bond lengths and the presence of adsorbates. It is widely used in surface science and has also been used to study polymers and magnetic materials. NEXAFS is synonymous with XANES (X-ray Absorption Near Edge Structure) but NEXAFS by convention is usually reserved for soft X-ray spectroscopy (photon energy less than 1000 electron volts). NEXAFS is distinguished from the closely related EXAFS method in that NEXAFS concentrates on fine structure within about 30 eV of the absorption edge while EXAFS considers the extended spectrum out to much higher electron kinetic energies. ...more on Wikipedia about "NEXAFS"

An overlayer is a layer of adatoms adsorbed onto a surface, for instance onto the surface of a single crystal. ...more on Wikipedia about "Overlayer"
PIXE (Particle-Induced X-ray Emission or Proton Induced X-ray Emission) is a technique used in the determining of the elemental make-up of a material or sample. When a material is exposed to an ion beam, atomic interactions occur that give off EM radiation of wavelengths in the x-ray part of the electromagnetic spectrum specific to a element. ...more on Wikipedia about "PIXE"
Surface charge is the electric charge present at an interface, for instance on the surface of a semiconductor material, or for example, on the surface of a protein. ...more on Wikipedia about "Surface charge"
Surface chemistry is the study of chemical phenomena that occur at the interface of two phases, usually between a gas and a solid or between a liquid and a solid. ...more on Wikipedia about "Surface chemistry"
Surface energy quantifies the disruption of chemical bonds that occurs when a surface is created. In the physics of solids, surfaces must be intrinsically less energetically favourable than the bulk of a material; otherwise there would be a driving force for surfaces to be created, and surface is all there would be (see sublimation (physics)). Cutting a solid body into pieces disrupts its bonds, and therefore consumes energy. ...more on Wikipedia about "Surface energy"
