The interplay between structural and electronic degrees of freedom in complex materials is
the subject of extensive debate in physics and materials science. Particularly interesting …

Charge-stripe order has recently been established as an important aspect of cuprate high-T
c superconductors. However, owing to the complex interplay between competing phases …

The state of the art concerning tunnel measurements of energy gaps in cuprate oxides has
been analyzed. A detailed review of the relevant literature is made, and original results …

Soon after the discovery of the first high-temperature superconductor by Georg Bednorz and
Alex Müller in 1986, the late Sir Nevill Mott in answering his own question'Is there an …

We investigate infrared manifestations of the pseudogap in the prototypical cuprate and
pnictide superconductors, YBa 2 Cu 3 O y and BaFe 2 As 2 (Ba122) systems. We find …

The ladder-chain compound (Sr, Ca) 14 Cu 24 O 41 is a semiconductor at ambient pressure,
but becomes a bulk superconductor above the pressure of about 3 GPa. Since the …

Ion-flow-stimulated roughening transition is a phenomenon that may prove useful in the
hierarchical structuring of nanostructures. In this work, we have investigated theoretically …

The self-organized dopant percolative filamentary model, entirely orbital in character (no
fictive spins), explains quantitatively and uniquely chemical trends in superconductive …

Low-temperature scanning tunneling microscopy and/or scanning tunneling spectroscopy
measurements of heavily overdoped Bi 2− x Pb x Sr 2 CuO y have revealed nanoscale …

Scanning tunneling microscopy/spectroscopy (STM/STS) measurements were carried out on
a multilayered cuprate superconductor Ba 2 Ca 5 Cu 6 O 12 (O 1− x, F x) 2. STM topography …
