Tetragonal CuO: A new end member of the 3d transition metal monoxides (2008)
Siemons, Wolter, Koster, Gertjan, Blank, Dave H. A., Hammond, Robert H., Geballe, Theodore H., Beasley, Malcolm R.
Monoclinic CuO is anomalous both structurally as well as electronically in the 3$d$ transition metal oxide series. All the others have the cubic rock salt structure. Here we report the synthesis and...
Superconductivity in zigzag CuO chains (2007)
Berg, Erez, Geballe, Theodore H., Kivelson, Steven A.
Superconductivity has recently been discovered in Pr$_{2}$Ba$_{4}$Cu$_{7}$O$_{15-\delta}$ with a maximum $T_c$ of about 15K. Since the CuO planes in this material are believed to be insulating, it...
Siemons, Wolter, Koster, Gertjan, Yamamoto, Hideki, Harrison, Walter A., Lucovsky, Gerald, Geballe, Theodore H., ...
As discovered by Ohtomo and Hwang, a large sheet charge density with high mobility exists at the interface between SrTiO3 and LaAlO3. Based on transport, spectroscopic, and oxygen-annealing...
Siemons, Wolter, Koster, Gertjan, Yamamoto, Hideki, Geballe, Theodore H., Blank, Dave H.A., Beasley, Malcolm R.
We have made very thin films of LaAlO3 on TiO2 terminated SrTiO3 and have measured the properties of the resulting interface in various ways. Transport measurements show a maximum sheet carrier...

What Tc can teach about superconductivity (2006)
Geballe, Theodore H., Koster, Gertjan
We compare the Tcs found in different families of optimally-doped High-Tc cuprates and find, contrary generally accepted lore, that pairing is not exclusively in the CuO2 layers. Evidence for...
Electronic properties of buried hetero-interfaces of LaAlO3 on SrTiO3 (2006)
Siemons, Wolter, Koster, Gertjan, Yamamoto, Hideki, Harrison, Walter A., Geballe, Theodore H., Blank, Dave H. A., ...

Workshop on the Road to Room Temperature Superconductivity. (1998)
History shows right from the beginning that there has been no successful prediction of new families of superconductors. Discoveries in this field have been unexpected, even revolutionary, and not...
Fabrication and Analysis of Josephson and Weak-Link Junctions and Arrays. (1998)
Kapitulnik, Aharon, Geballe, Theodore H.
The work took two main avenues in order to prepare the ground for the main goal of the program: planar junctions made with the use of scanning tunneling microscope and atomic force microscopes in...
Thermionic Cooling Devices (1998)
Kenny, Thomas, Geballe, Theodore H.
The work functions of Au and Nb films with and without O2 implantation and with Cs film coatings were measured Work functions with values in the range of 1.2-1.3 eV on Nb and Au surfaces coated with...
