“Elemental tellurium is a small band-gap semiconductor, which is always p-doped due to the natural occurrence of vacancies. Its chiral non-centrosymmetric structure, characterized by helical chains ...

(Nanowerk Spotlight) Electronic devices work through precise control over the flow of electricity. While typical materials act as either conductors or insulators, the ability to switch between these ...

Physicists can observe quantum mechanical phase transitions using ultracold atoms (yellow) in optical lattices (white surface). Originally, the existence of phase transitions was predicted for certain ...
