Ridley Watkins Hilsum theory
From Wikipedia, the free encyclopedia
According to the Ridley Watkins Hilsum (RWH) Theory the differential negative resistance that is developed in a bulk solid state III - V compound when either a voltage or a current is applied to the terminals of the sample.
There are two modes of negative resistance devices:
1. Voltage-controlled modes. 2. current-controlled modes.
In the voltage controlled mode the current density can be multivalued, whereas in the current controlled mode the voltage can be multivalued. In 1964 Kroemer suggested that Gunn's observations were in complete agreement with the RWH.
