Mobility-dependent Low-frequency Noise in Graphene Field Effect Transistors
Yan Zhang, E. E. Mendez, Xu Du
We have investigated the low-frequency 1/f noise of both suspended and on-substrate graphene field-effect transistors and its dependence on gate voltage, in the temperature range b…
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…
Shot noise of large charge quanta in superconductor/semiconductor/superconductor junctions
F. E. Camino, V. V. Kuznetsov, E. E. Mendez +3
We have found experimentally that the noise of ballistic electron transport in a superconductor/semiconductor/superconductor junction is enhanced relative to the value given by the…
Hopping Conductivity Beyond The Percolation Regime Probed By Shot-Noise Measurements
F. E. Camino, V. V. Kuznetsov, E. E. Mendez +4
We have observed suppression of shot noise in the variable-range hopping regime for a two-dimensional electron gas whose localization length, xi, is controlled by a gate voltage. W…
