Scientists have discovered a centrosymmetric crystal that behaves as though it is chiral – absorbing left- and right-handed ...

The crystal is made of lithium, cobalt, selenium and oxygen, with the cobalt giving rise to the crystal's purple color. Credit: Kendall Kamp/Northwestern University.

Scientists from Immanuel Kant Baltic Federal University in frames of academic mobility between China and Russia together with colleagues from Qiqihar University grew "defective" crystals of tin ...

The sulfur atoms replaced the selenium atoms in the crystals to form molybdenum disulfide, which has a nearly identical crystal structure. The two semiconductor crystals formed sharp junctions, ...

The fastest selenium clusters, with energies of 42 electron volts (eV) per atom, ripped through the monolayer; they needed to be controllably slowed to implant into the top ply.

Niobium selenide crystals are usually synthesized by heating niobium and selenium in a sealed quartz tube until long whiskers or ribbons form. Satoshi Tanda and co-workers at Hokkaido University in ...

Pressure variations in the chamber caused the selenium to cycle between liquid and vapor. Under those conditions, the two metals combine into whiskerlike crystals that attach to the surface of ...

IN a recent communication1, measurements of conductivity and thermo-electric power of selenium single crystals were reported. These have now been supplemented by a determination of the Hall effect ...

The tiny drops of liquid selenium acted as spools on which the strips formed (see image). As the crystals of NbSe 3 grew, they wrapped around the droplet and the two ends met, making a seamless ...
