Drastic Reduction of Shot Noise in Semiconductor Superlattices
W. Song, A. K. M. Newaz, J. K. Son +1
We have found experimentally that the shot noise of the tunneling current through an undoped semiconductor superlattice is reduced with respect to the Poissonian noise value $2…

Shot-noise characteristics of triple-barrier resonant-tunneling diodes
A. K. M. Newaz, W. Song, Y. Lin +2
We have found experimentally that the shot noise in InAlAs-InGaAs-InAlAs Triple-Barrier Resonant-Tunneling Diodes (TBRTD) is reduced over the 2eI Poissonian value whenever their di…

Unusual Tunneling Characteristics of Double-quantum-well Heterostructures
Y. Lin, J. Nitta, ; A. K. M. Newaz +2
We report tunneling phenomena in double InGaAs quantum-well structures that are at odds with the conventional parallel-momentum-conserving picture of tunneling be…
