The smallest in the world
The smallest in the world
The Japanese Himeji Institute of Technology, NEC Corporation and researchers from Seiko Instruments have produced the world's smallest wine glass. The cup has a diameter of 2,750 nanometers -200,000 times lower than usual - and is carbon. Therefore, they have been able to realize a three-dimensional object on a nanometric scale.
This three-dimensional production technique will benefit manufacturers who are preparing next-generation electronic material. In fact, moving from microns to nanometers is becoming increasingly difficult to make structures of high precision. The new technique will allow the realization of biosensors, high-performance optical communications devices, control switches, etc. in ultravinatura. It is considered that the new technique can also be used in other areas, nano-electromechanical, nanooptics, nanomagnetic devices, bionanotxips, etc.
For the realization of this type of small structures it would be necessary to use the two-dimensional techniques currently employed in the manufacture of semiconductors. But this technique would have great drawbacks. In fact, lasers used in optical structuring techniques are inaccurate in structures below a micron.
For the realization of the Wine Cup, researchers have projected the ion beam in the gallium by computer-controlled electromagnetic deflection.
