The term contact resistance refers to the contribution to the total resistance of a material which comes from the electrical leads and connections as opposed to the intrinsic resistance, which is an inherent property, independent of the measurement method. The idea of potential drop on the injection electrode was introduced by William Shockley to explain the difference between the experimental results and the model of gradual channel approximation. The name "contact resistance" was decided for the consideration of the metal–semiconductor interface as a main contribution to this phenomenon. Beside that also "interface resistance", "transitional resistance", or just simply "correction term" were used. Therefore was later used term "parasitic resistance" as a more general term, where it is usually still assumed that the contact resistance has a major contribution.

Famous quotes containing the words contact and/or resistance:
“Words, words, words! They shut one off from the universe. Three quarters of the time one’s never in contact with things, only with the beastly words that stand for them.”
—Aldous Huxley (1894–1963)
“He made no resistance whatever, and was stabbed in the back.... I must not dwell upon the fearful repast.... Words have no power to impress the mind with the exquisite horror of their reality.”
—Edgar Allan Poe (1809–1849)
