This review addresses resistive switching devices operating according to the bipolar
valence change mechanism (VCM), which has become a major trend in electronic materials …

Doped SrTiO 3, one of the most dilute bulk systems to display superconductivity, is perhaps
the first example of an unconventional superconductor, as it does not fit into the standard …

Oxygen vacancies play crucial roles in determining the physical properties of metal oxides,
representing important building blocks in many scientific and technological fields due to their …

The properties of quantum materials are commonly tuned using experimental variables such
as pressure, magnetic field and doping. Here we explore a different approach using …

SrTiO3, a quantum paraelectric, becomes a metal with a superconducting instability after
removal of an extremely small number of oxygen atoms. It turns into a ferroelectric upon …

The nature of superconductivity in SrTiO3, the first oxide superconductor to be discovered,
remains a subject of intense debate several decades after its discovery. SrTiO3 is also an …

Recently, ferroelectric tunnel junctions have attracted much attention due to their potential
applications in non-destructive readout non-volatile memories. Using a semiconductor …

It has been known for more than a decade that phonons can produce an off-diagonal
thermal conductivity in the presence of a magnetic field. Recent studies of thermal Hall …

The Nernst effect is the transverse electric field produced by a longitudinal thermal gradient
in the presence of a magnetic field. At the beginning of this century, Nernst experiments on …

We present a study of thermal conductivity, κ, in undoped and doped strontium titanate in a
wide temperature range (2–400 K) and detecting different regimes of heat flow. In undoped …
