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…

Magnetotunneling Between Two-dimensional Electron Gases in InAs-AlSb-GaSb Heterostructures
Y. Lin, E. M. González, E. E. Mendez +3
We have observed that the tunneling magnetoconductance between two-dimensional (2D) electron gases formed at nominally identical InAs-AlSb interfaces most often exhibits two sets o…
