Abstract
We report new experimental results on the heterostructure hot-electron diode. Improved structures, grown by metalorganic chemical vapor deposition, incorporate a single rectangular tunneling barrier of AlAs adjacent to a GaAs drift region which provides a large Γ conduction-band offset. These devices exhibit significant S-shaped negative differential resistance and dc switching at 300 K.
