... gap — equally spaced above and below the Fermi level — is a strong indication that electrons are paired up. That superconducting gap exists at and below the transition temperature, as long as a ...
... as a result of the doping and the cooling, the material turns into a superconductor, with the doped electrons pairing up to effortless carry electricity. But how, and where in the material, does this ...
... at the same time."
To understand this effect, the scientists have proposed a new type of electron pairing. "We've found that the electrons form much stronger pairs if they team up with one of the ...
... (0 kelvin, or -273 degrees Celsius), electrons carry current by forming so-called Cooper ... 'traffic-jam' effect while having stronger electron pairing," Davis said. Techniques developed for the current ...
... "That doesn't normally occur in other geological materials that we know about."
The degree of electron pairing, also known as electronic spin state, can affect how well the materials conduct heat and ...
... horizon—superconductivity—but we cannot yet see inside to understand why."
A new mechanism for the electron-pairing glue that gives rise to superconductivity could allow researchers to design new ...
... 822] Press Release]. But a similar approach might be used to facilitate the movement of electron pairs between layers, Tranquada said.
One of the key measurements, made by Brookhaven physicist Qiang ...
... from one electron orbital to another.
"Our results suggest that the mechanism that makes electrons pair together could be provided by antiferromagnetic fluctuations rather than lattice vibrations," ...
... structure of the so-called superconducting gap, which in turn depends on the microscopic mechanism of how electron pairs are formed," said Prozorov. "London penetration depth is one of the primary ...
... .
"The spectroscopic 'fingerprint' confirms that, at these higher temperatures, electrons are pairing up as they must in a superconductor, but for some reason they are not co-operating coherently to ...
