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 in water.There are multiple factors generating surface charge. First of all, surface charge… … Wikipedia
Surface conductivity — is an additional electric conductivity of fluid in the vicinity of the charged surface. Fluid conductivity is associated with ions motion in electric field. Concentration of ions is higher close to the charged surfaces. They are attracted there… … Wikipedia
Electric displacement field — In physics, the electric displacement field, denoted as , is a vector field that appears in Maxwell s equations. It accounts for the effects of free charges within materials. D stands for displacement, as in the related concept of displacement… … Wikipedia
Charge density — The linear, surface, or volume charge density is the amount of electric charge in a line, surface, or volume, respectively. It is measured in coulombs per meter (C/m), square meter (C/m²), or cubic meter (C/m³), respectively, and represented by… … Wikipedia

Surface enhanced Raman spectroscopy — Surface Enhanced Raman Spectroscopy, or Surface Enhanced Raman Scattering, often abbreviated SERS, is a surface sensitive technique that results in the enhancement of Raman scattering by molecules adsorbed on rough metal surfaces. The enhancement … Wikipedia
Surface plasmon — Surface plasmons, also referred to in the literature as surface plasma polaritons, are fluctuations in the electron density at the boundary of two materials. Plasmons are the collective vibrations of an electron gas (or plasma) surrounding the… … Wikipedia
Surface photovoltage — (SPV) measurements are a widely used method to determine the minority carrier diffusion length of semiconductors. Since the transport of minority carriers determines the behavior of the p n junctions that are ubiquitous in semiconductor devices,… … Wikipedia
