(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 ...

Given an oscillating electric signal, rectification results in a direct-current signal and frequency doubling results in a signal oscillating at twice the frequency of the input. Traditionally, this ...

“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 ...
