Details of A optoelettronico device

It has been recently put to point, from a team of investigators of the Georgia Institute of Technology, a optoelettronico device that, acting on nanometrica scale, resolves many complex logical operations. The peculiarity of this quantistico device is its ability to produce to a leggibile optical escape without the aid of some contact electrical worker.

The device is based on griglie of nanocluster of silver and could give origin to a new quantistico computer on molecular scale. According to biochemist Robert Dickson this search has demonstrated the mechanism of a optoelettronico transistor in which it comes proportionally measured the elettroluminescente escape to the voltage in income, to difference of the normal electronic transistors in which measure the current in escape. In practical, the quantistico device works in the same way of the normal transistors, but not with the current electrical worker but with the light.

The possessed levels of energy from the nanocluster are diversified. In this way the activation can happen individually with the variation of the voltage applied to the grill. Siccome the apparatus does not have need of logons isolated electrical workers for every nanocluster, its fabrication on nanometrica scale is easy to realize regarding the traditional systems. The search has been published from the periodical "Proceedings of the National Academy of Sciences" (PNA).
