Friction Control in Apparatus Having Wide Bandgap Semiconductors

摘要

Apparatus comprising, in use, a wide bandgap semiconductor, a conductor which is moveable relative to the semiconductor and means for applying a potential across the junction between a conductor and semiconductor to control the friction generated by the relative movement between the semiconductor and the conductor. A method of controlling friction between a wide bandgap semiconductor and conductor which are moveable relative to each other comprising applying a potential across the junction between the semiconductor and the conductor.
