Antiferrodistortive and ferroeletric phase transitions in freestanding films of SrTiO3
Epitaxially grown thin films are commonly used to strain engineer electronic properties by the choice of a substrate, and therefore do not match bulk properties (leading to properties that deviate from the bulk material). Free standing ultrathin oxide films are expected to preserve the bulk-like properties due to the absence of substrate influence. However, we show that this expectation is not fulfilled with ultrathin free standing SrTiO3, as they get ferroelectric at 80K.
Prestigious funding for research at PSI
Concrete, chemical catalysis and the search for new physics – three PSI researchers have each received a grant from the Swiss National Science Foundation for these areas of research.
