Andreev scattering and conductance enhancement in mesoscopic semiconductor-superconductor junctions
Niels Asger Mortensen, Antti-Pekka Jauho, Karsten Flensberg
An inherent difficulty in studying mesoscopic effects in semiconductor--superconductor hybrid structures is the large Schottky barrier which often forms at the interface. A large t…
Screening, nonadiabaticity, and quantized acoustoelectric current
M. Pustilnik, K. Flensberg, Q. Niu
Quantized single-electron transport driven by surface acoustic waves (SAW) through a pinched-off narrow constriction is studied theoretically. Long-range Coulomb interaction causes…
Dephasing in semiconductor-superconductor structures by coupling to a voltage probe
Niels Asger Mortensen, Antti-Pekka Jauho, Karsten Flensberg
We study dephasing in semiconductor-superconductor structures caused by coupling to a voltage probe. We consider structures where the semiconductor consists of two scattering regio…
Non-adiabaticity and single-electron transport driven by surface acoustic waves
Karsten Flensberg, Qian Niu, Michael Pustilnik
Single-electron transport driven by surface acoustic waves (SAW) through a narrow constriction, formed in two-dimensional electron gas, is studied theoretically. Due to long-range…
Contact resistance of quantum tubes
Niels Asger Mortensen, Kristinn Johnsen, Antti-Pekka Jauho +1
We consider the conductance of a quantum tube connected to a metallic contact. The number of angular momentum states that the tube can support depends on the strength of the radial…
Conductance enhancement in quantum point contact-semiconductor-superconductor devices
Niels Asger Mortensen, Antti-Pekka Jauho, Karsten Flensberg +1
We present numerical calculations of the conductance of an interface between a phase-coherent two-dimensional electron gas and a superconductor with a quantum point contact in the…
