‘Pressed’ light may produce breakthroughs in nano-sized electronics

It is one thing that is produced nano devicesStudying and improving these things is another matter – they are too small and can’t reflect enough light to look good. However, a hack might make that possible. University of California Riverside researchers we built Technology that compresses tungsten lamp light into a 6-nm spot at the end of a silver nanowire. This allows scientists to produce color images at an “unprecedented” level, rather than having to be satisfied with molecular vibrations.

The developers have modified the existing “ultra-focus” instrument (already used to measure vibrations) to detect signals across the entire visible spectrum. The light travels in a conical path similar to a flashlight. When the tip of the nanowire passes over an object, the system records the effect of that element on the shape and color of the beam (including through the spectrophotometer). With two spectrophotometers per 6 nanometer pixel, the team can create color images of carbon nanotubes that will appear gray.

This ability to compress light is notable in itself, but the inventors see it as playing an important role in nanotechnology. Semiconductor producers could develop more uniform nanomaterials that find their way into chips and other densely packed devices. Pressurized light can also improve humanity’s understanding of nanoelectronics, quantum optics And other scientific fields in which this decision was not available.
