We investigate the source of the variation of the pairing strength in high-Tc superconductors. We have developed a new
technique that allows us to study the same nanoscale region of the material... Read more...
We take an atom-by-atom look at where pairing gaps form in the cuprate superconductor BSCCO. When pairing occurs in a
superconductor, a gap forms in the density of states (DOS) that can be probed by... Read more...
A novel technique developed by our group uses a scanning tunneling microscope (STM) to substitute atoms into a semiconductor
one atom at a time. This technique has been used to assemble a magnetic... Read more...
We performed a scanning tunneling spectrocopy characterization of the electronic correlations in the pseudogap state in a
high-Tc superconductor. Heating a normal superconductor above its critical... Read more...
Using a scanning tunneling microscope, we demonstrated that a single copper-oxide plane can form a stable layer at the
superconductor's surface. This plane behaves differently when exposed at the... Read more...
Scientists recently discovered that nanoscopic peapods – the latest class of nanomaterials created by filling the cores of
single-wall nanotubes – have tunable electronic properties. Our measurements show that encapsulation... Read more...
