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 dependences of resistances of good and bad contacts, regardless of the physical cause of the poor contact.
