K. Alex Müller: Science between ferroelectricity and superconductivity
R. K. Kremer, A. Bussmann-Holder, H. Keller
K. Alex Müller started his scientific career in 1958 when he was about thirty-one years old. After his wife passed away and being in his nineties, his interest in physics gradually…
K. Alex Müller and his important role in ferroelectricity
Annette Bussmann-Holder, Hugo Keller
In this review we concentrate on the work of K. Alex Müller in connection with his activities on oxide perovskites and ferroelectrics which were central to his research career long…
Filamentary superconductivity of resistively-switched strontium titanate
K. Szot, C. Rodenbücher, K. Rogacki +7
SrTiO, although a wide gap insulator, has long been known to become metallic and superconducting at extremely low doping levels. This has given rise to questions concerning the…
Multi-Band Superconductivity and the Steep Band -- Flat Band Scenario
Annette Bussmann-Holder, Hugo Keller, Arndt Simon +1
The basic features of multi-band superconductivity and its implications are derived. In particular, it is shown that enhancements of the superconducting transition temperature take…
High-temperature superconductors: underlying physics and applications
Annette Bussmann-Holder, Hugo Keller
Superconductivity was discovered in 1911 by Kamerlingh Onnes and Holst in mercury at the temperature of liquid helium (4.2 K). It took almost 50 years until in 1957 a microscopic t…
Unconventional co-existence of insulating nano-regions and conducting filaments in reduced SrTiO3: mode softening, local piezoelectricity and metallicity
Annette Bussmann-Holder, Hugo Keller, Arndt Simon +2
Doped SrTiO3 becomes a metal at extremely low doping concentrations n and is even superconducting with the superconducting transition temperature adopting a dome-like shape with th…
