Question 1
Electronic Devices & CircuitsSemiconductor Devices

A metal-semiconductor contact designed to behave approximately as a non-rectifying low-resistance connection is called an?

  • AOhmic contact
  • BAvalanche junction
  • CTunnel barrier oscillator
  • DPhotovoltaic junction
Report an error
Correct Answer: A. Ohmic contact
Explanation: An ohmic contact is engineered so current can flow readily in both directions with approximately linear current-voltage behavior over its intended range.
