Is the `Finite Bias Anomaly' in planar GaAs-Superconductor junctons caused by point-contact like structures?
S. Chaudhuri, P. F. Bagwell, D. McInturff +6
We correlate transmission electron microscope (TEM) pictures of superconducting In contacts to an AlGaAs/GaAs heterojunction with differential conductance spectroscopy performed on…

Ballistic Transport and Andreev Resonances in Nb-In Superconducting Contacts to InAs and LTG-GaAs
T. Rizk, A. Yulius, W. I. Yoo +6
We have formed superconducting contacts in which Cooper pairs incident from a thick In layer must move through a thin Nb layer to reach a semiconductor, either InAs or low temperat…
