Ytförlust
Ytförlust is a Swedish term meaning “surface loss” and is used informally across several fields to describe loss of material, energy, or information at a surface or boundary. The word combines yt, referring to a surface, and förlust, meaning loss. It is not a standardized technical term with a single fixed definition; its precise meaning depends on the discipline.
In materials science and tribology, ytförlust describes material worn away from a surface during sliding or
In electronics and semiconductor physics, ytförlust can refer to surface recombination losses, where charge carriers recombine
In optics, ytförlust denotes losses due to surface scattering or absorption associated with surface roughness, contamination,
Measurement approaches vary by field: wear testing and profilometry in tribology; carrier lifetime and surface passivation
