Shot Noise in Mesoscopic Transport Through Localised States
A. K. Savchenko, S. S. Safonov, S. H. Roshko +5
We show that shot noise can be used for studies of hopping and resonant tunnelling between localised electron states. In hopping via several states, shot noise is seen to be suppre…
Enhanced shot noise in resonant tunnelling via interacting localised states
S. S. Safonov, A. K. Savchenko, D. A. Bagrets +4
In a variety of mesoscopic systems shot noise is seen to be suppressed in comparison with its Poisson value. In this work we observe a considerable enhancement of shot noise in the…
Metallic and insulating behaviour of the two-dimensional electron gas on a vicinal surface of Si MOSFETs
S. S. Safonov, S. H. Roshko, A. K. Savchenko +2
The resistance R of the 2DEG on the vicinal Si surface shows an unusual behaviour, which is very different from that in the (100) Si MOSFET where an unconventional metal to insulat…
Tomography of Quantum Spinor States
Sergey S. Safonov
A possibility of describing two-level atom states in terms of positive probability distributions (analog to the symplectic tomography scheme) is considered. As a result the basis o…
