Researchers Observe Semiconductor-Metal Transition Using Ultrafast Electron Diffraction

Researchers at McGill University have conducted ultrafast electron diffraction experiments to study the semiconductor-metal transition of vanadium dioxide (VO2), during which they observed the reorganizations of the atomic positions of the material and its electron distribution, simultaneously. This transformation occurs at femtosecond time scales, which is in the range of one millionth of a billionth of a second. [More]
