Hiya fediverse, happy Friday. Here's your semi-occasional dose of #terahertz content:

A #terahertz #image of a single #semiconductor #nanowire, taken about three #picoseconds after it was optically excited (spatial #resolution of image ~ 50 nanometers). It is brighter in the middle due to the mobile #electrons that are still floating around in there. The edges are darker because electrons near the edges can become trapped more readily.
