Electric-field-induced pyroelectric order and localization of the confined electrons in LaAlO3/SrTiO3 heterostructures
M. Rössle, K. W. Kim, A. Dubroka +13
With infrared ellipsometry, x-ray diffraction, and electric transport measurements we investigated the electric-field-effect on the confined electrons at the LaAlO3/SrTiO3 interfac…

Large Negative Electronic Compressibility of LaAlO3-SrTiO3 Interfaces with Ultrathin LaAlO3 Layers
V. Tinkl, M. Breitschaft, C. Richter +1
A two-dimensional electron liquid is formed at the n-type interface between SrTiO3 and LaAlO3. Here we report on Kelvin probe microscopy measurements of the electronic compressibil…

Field-Effect Devices Utilizing LaAlO-SrTiO Interfaces
B. Förg, C. Richter, J. Mannhart
Using LaAlO-SrTiO bilayers, we have fabricated field-effect devices that utilize the two-dimensional electron liquid generated at the bilayers' {\textit n}-type interfaces…
