As the researchers changed the voltage across the tunnel diode
, they observed large fluctuations in current due to the appearance and disappearance of wave function scars.
Scientists first convincingly demonstrated the electronic tunnelling phenomenon in semiconductors in the late 1950s, and since that time it has become the basis of several electronic components--among them tunnel diodes
, which are good for some amplification and high-speed switching applications.
NSC's President, Michael Grollman, stated, "This tunnel diode
CIP patent underpins a considerable portion of our recent efforts.
Graham Clark, Director of Global Sales and Marketing, said, "The recent results obtained from our short loop tunnel diode
experiment show that the CMOS process we are developing for this technology is experimentally viable.
