Abstract
A device having two opposite terminals interconnected by material layers for switching between a current conducting state and a state blocking transport of charge carriers between the terminals upon applying a voltage there across has as the material layers a first layer made of intrinsic diamond and a second layer arranged next to the first layer. The device switches to the conducting state by providing free charge carriers in the second layer for transport through the diamond layer through the voltage and the blocking state by stopping providing the free charge carriers for the transport. The diamond layer is adapted to take a major part of the voltage across the terminals in the blocking state.
