Point-contact transistor — A point contact transistor was the first type of solid state electronic transistor ever constructed. It was made by researchers John Bardeen and Walter Houser Brattain at Bell Laboratories in December of 1947. They were working with physicist… … Wikipedia
Contact resistance — 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… … Wikipedia
Contact electrification — is an obsolete scientific theory from the Enlightenment that attempted to account for all the sources of electric charge known at the time.[1] In the late 18th century, scientists developed sensitive instruments for detecting electrification ,… … Wikipedia
Ohmic contact — An ohmic contact is a region on a semiconductor device that has been prepared so that the current voltage (I V) curve of the device is linear and symmetric. If the I V characteristic is non linear and asymmetric, the contact is not ohmic, but is… … Wikipedia
