Metastable defects decrease the fill factor of solar cells
Thomas Paul Weiss, Omar Ramírez, Stefan Paetel +4
Cu(In,Ga)Se2 based solar cells exceed power conversion efficiencies of 23 %. Yet, the fill factor of these solar cells, with best values around 80 %, is relatively low (Si reaches…
LaAlO3 stoichiometry found key to electron liquid formation at LaAlO3/SrTiO3 interfaces
M. P. Warusawithana, C. Richter, J. A. Mundy +17
Emergent phenomena, including superconductivity and magnetism, found in the two-dimensional electron liquid (2-DEL) at the interface between the insulators LaAlO3 and SrTiO3 distin…
Evolution of the interfacial structure of LaAlO3 on SrTiO3
S. A. Pauli, S. J. Leake, B. Delley +7
The evolution of the atomic structure of LaAlO3 grown on SrTiO3 was investigated using surface x-ray diffraction in conjunction with model-independent, phase-retrieval algorithms b…
Large capacitance enhancement and negative compressibility of two-dimensional electronic systems at LaAlO/SrTiO interfaces
Lu Li, C. Richter, S. Paetel +3
Novel electronic systems forming at oxide interfaces comprise a class of new materials with a wide array of potential applications. A high mobility electron system forms at the LaA…
Diodes with Breakdown Voltages Enhanced by the Metal-Insulator Transition of LaAlO-SrTiO Interfaces
R. Jany, M. Breitschaft, G. Hammerl +10
Using the metal-insulator transition that takes place as a function of carrier density at the LaAlO-SrTiO interface, oxide diodes have been fabricated with room-temperature…
Two-dimensional electron liquid state at LaAlO3-SrTiO3 interfaces
M. Breitschaft, V. Tinkl, N. Pavlenko +8
Using tunneling spectroscopy we have measured the spectral density of states of the mobile, two-dimensional electron system generated at the LaAlO3-SrTiO3 interface. As shown by th…
