The advent of the world’s smallest transistor: molecular size only

On the road to save Moore’s Law, everybody seems to have mustering the strength. Not long ago, IBM announced the development of a successful 7nm chips, and now, there are research and development team claims successful preparation smallest transistors ever – only the size of a single molecule.

To achieve this amazing achievement from a German, Japan and the US joint research team, they used 12 of indium atoms around a positively charged molecule on the phthalocyanine indium arsenide crystal substrate, and then got a transistor .

http://www.oemie.com is an independent distributor 6 years old, more than 300 thousand electronic components can be found at our web datadase, such as qqb575r30t1000 and ZXCT1022E5TA, hard to find and obsolete electronic components is our leading business, looking for to cooperate with all company or personal who want to buy electronic parts.

As early as 2012, IBM has stated that the success of a single bit of information will be integrated into the structure of 12 atoms, and successful preparation of this transistor is a huge leap forward in this basis. The transistor diameter of just 167 picometers (10-12 meters), the smallest circuit than the previous 42 times smaller.

Based on this achievement researchers unexpectedly found that the phthalocyanine molecule orientation will be its impact on the charge, and by limiting the movement of electron flow indium atomic scanning tunneling electron microscope, the indium atoms confined precisely within a specific grid .

But this research is still in its early stages, practical use in the distant future, but this research has paved the way for large-scale quantum computing, but the specific situation to be further verified.
