Abstract
Resonant tunneling between closely spaced two dimensional electron gases is a
single particle phenomenon that has sparked interest for decades. High
tunneling conductances at equal electron densities are observed whenever the
Fermi levels of the two quantum wells align. Detuning the Fermi levels out of
the resonant 2D-2D tunneling regime causes a negative differential resistance.
The negative differential resistance leads to a hysteresis when operating the
device in a current driven mode, allowing a bilayer system to function as a
volatile memory resistor.
