Abstract :
Fabrication of a CHIRP (coherent heterointerfaces for reflection and penetration) superlattice device is presented. Negative differential resistance (NDR) is observed at around 85 K. This NDR is found only in one bias polarity and is not found when the bias is reversed, which is characteristic of CHIRP superlattices.
