Dependence of Contact Resistance on Current for Good and Bad Ohmic Contacts to Quantized Hall Resistors
Published
Author(s)
Kevin C. Lee
Abstract
Dependence of contact resistance on current has been measured for a large number of ohmic contacts to quantized Hall resistors under quantum Hall effect conditions. A definite trend is observed in the current dependencies of resistances of good and bad contacts, regardless of the physical cause of the poor contact.
