Directly imaging quantum states in two-dimensional materials

When some semiconductors absorb light, excitons (or particle pairs made of an electron bound to an electron hole) can form. Two-dimensional crystals of tungsten disulfide (WS2) have unique exciton states that are not found ...

Molding two-dimensional organic molecule crystals

Recently, a group of illegal counterfeiters was apprehended for producing around 400 fake luxury jewelry items using molds. They were able to create hundreds of faked luxury items simply after pouring molten metal into molds ...

Physicists discover an exotic material made of bosons

Take a lattice—a flat section of a grid of uniform cells, like a window screen or a honeycomb—and lay another, similar lattice above it. But instead of trying to line up the edges or the cells of both lattices, give the ...

Physicists find unusual waves in nickel-based magnet

Perturbing electron spins in a magnet usually results in excitations called "spin waves" that ripple through the magnet like waves on a pond that's been struck by a pebble. In a new study, Rice University physicists and their ...
