Workshop 5
Emergent States at Interfaces of Complex Oxides: What Can Be Learned from Local Probes
Wed. May 7, afternoon
Thu. May 8, morning
E1100/E1200
Organizers: Matthias Bode (CNM) and Anand Bhattacharya (CNM)
To agenda > Updated 3/20/2008
Two-dimensional electron gas (2-DEG) systems set the stage for some of the best-known manifestations of strong correlations, ranging from quantum-hall states in high mobility 2-DEGs to high-temperature superconductivity in the two-dimensional cuprates. Recent improvements in growing complex oxides by a suitable arrangement of digital layers within a heterostructure allow the realization of 2-DEGs without introducing chemical disorder.
The symposium shall identify promising materials, open problems, and adequate analysis tools that may lead to a better understanding of structural, electronic, and magnetic properties of these materials and their interfaces, including electron-beam--based (SEM, STEM-EELS) as well as near-field scanning probe techniques (MFM, STM/STS).
