Journal ArticleDOI
Origin of Charge Density at LaAlO3 on SrTiO3 Heterointerfaces: Possibility of Intrinsic Doping
Wolter Siemons,Wolter Siemons,Gertjan Koster,Hideki Yamamoto,Hideki Yamamoto,Walter A. Harrison,Gerald Lucovsky,Theodore H. Geballe,Dave H. A. Blank,M. R. Beasley +9 more
TL;DR: Based on transport, spectroscopic, and oxygen-annealing experiments, it is concluded that extrinsic defects in the form of oxygen vacancies introduced by the pulsed laser deposition process used by all researchers to date to make these samples is the source of the large carrier densities.
Journal ArticleDOI
Giant Proximity Effect in Cuprate Superconductors
TL;DR: Using an advanced molecular beam epitaxy system, atomically smooth films of high-temperature superconductors and uniform trilayer junctions with virtually perfect interfaces are synthesized and it is found that supercurrent runs through very thick barriers.
Journal ArticleDOI
Tetragonal CuO: end member of the 3d transition metal monoxides
Wolter Siemons,Wolter Siemons,Gertjan Koster,Gertjan Koster,Dave H. A. Blank,R. H. Hammond,Theodore H. Geballe,M. R. Beasley +7 more
TL;DR: In this article, the synthesis and electronic property determination of a tetragonal (elongated rocksalt) form of CuO created using an epitaxial thin-film deposition approach was reported.
Journal ArticleDOI
Cryogenic scanning Hall-probe microscope with centimeter scan range and submicron resolution
TL;DR: In this article, a Hall-probe microscope was constructed for efficient magnetic imaging of mesoscopic devices, media, and materials, operating from 4 K to room temperature with fast turn-around time.
Journal ArticleDOI
Imaging ac losses in superconducting films via scanning Hall probe microscopy
TL;DR: In this paper, the authors used magnetic imaging to reconstruct the electric field from the inductive portion determined by Faraday's law and then applied the procedures to images of a strip of a superconducting film carrying subcritical ac current.
