The results show that resistivity begins to decrease sharply at temperatures below 40 K regardless of the thickness of the FeSe layer. This means that two-dimensional superconductivity in FeSe/STO ...

Using laser light to trap atoms in a checkerboard-like pattern, a team led by Princeton scientists studied how resistance — the loss of electrical current as heat — can develop in unconventional ...

Copper, platinum, aluminum, gold. Metals have been so important in human history that we’ve named historical epochs (the Bronze Age, the Iron Age) for their transformative power. These materials, with ...
