A Compact Model of Threshold Switching Devices for Efficient Circuit Simulations
Mohamad Moner Al Chawa, Daniel Bedau, Ahmet S. Demirkol +4
In this paper, we present a new compact model of threshold switching devices which is suitable for efficient circuit-level simulations. First, a macro model, based on a compact tra…
Nonsaturating Dephasing Time at Low Temperature in an Open Quantum Dot
I. G. Rau, S. Amasha, M. Grobis +3
We report measurements of the electron dephasing time extracted from the weak localization (WL) correction to the average conductance in an open AlGaAs/GaAs quantum dot from 1 K to…
Spatially probed electron-electron scattering in a two-dimensional electron gas
M. P. Jura, M. Grobis, M. A. Topinka +3
Using scanning gate microscopy (SGM), we probe the scattering between a beam of electrons and a two-dimensional electron gas (2DEG) as a function of the beam's injection energy, an…
Coulomb Blockade in an Open Quantum Dot
S. Amasha, I. G. Rau, M. Grobis +3
We report the observation of Coulomb blockade in a quantum dot contacted by two quantum point contacts each with a single fully-transmitting mode, a system previously thought to be…
Universal Scaling in Non-equilibrium Transport Through a Single-Channel Kondo Dot
M. Grobis, I. G. Rau, R. M. Potok +2
Scaling laws and universality play an important role in our understanding of critical phenomena and the Kondo effect. Here we present measurements of non-equilibrium transport thro…
Kondo Effect in Mesoscopic Quantum Dots
M. Grobis, I. G. Rau, R. M. Potok +1
A dilute concentration of magnetic impurities can dramatically affect the transport properties of an otherwise pure metal. This phenomenon, known as the Kondo effect, originates fr…
Tuning Negative Differential Resistance in a Molecular Film
M. Grobis, A. Wachowiak, R. Yamachika +1
We have observed tunable negative differential resistance (NDR) in scanning tunneling spectroscopy measurements of a double layer of C60 molecules on a metallic surface. Using a si…
