When speech comes about a material having thickness in only one atom and having huge prospects for application in semiconductors and electronics, the first that occurs, the decanter is. But speech now will go not about the countess, and about the new material known as german which was created by scientists-chemists from Ohio university (Ohio State University). Germanan, as well as a decanter, has thickness in one atom, only its crystal lattice consists not of atoms of carbon, and atoms Germany. The whole set of exclusive properties of a new material does him by very perspective candidate for silicon replacement in semiconductor devices of the future.
Researchers and engineers used germaniye for creation of the first experimental chips more than 60 years ago, but later this material yielded the position to silicon, as to more widespread material, simpler in practical application. However, remarkable electric and semiconductor properties Germany force scientists again and again to pay the attention to this material. "The majority of people considers a decanter as the most perspective material for future electronics" - Joshua Goldberger (Joshua Goldberger), the scientist-chemist from Ohio university tells, - "But silicon and germaniye are materials of the present, their properties are perfectly studied for last 60 years. It is necessary to develop only new forms of these materials and new technologies that will allow to use further these materials in electronic industry, instead of to pass to the new materials which properties are still studied not up to the end".
Turned out one-nuclear germaniye carries out electrons ten times faster, than silicon, and five times quicker, than usual germaniye. It means that the conductor from such Germany, located on a chip crystal, will be able to pass through itself a bigger electric current. Germany is more chemically steady than silicon, it isn't oxidized at contact with air or water. In addition, it absorbs light that means big prospect of this material for use in solar batteries better.
Scientists though managed to receive earlier german, but it were very small quantities which are obviously insufficient for use of such material in mass production. And to receive german in large numbers Goldberger and his team developed a unique method.
In usual conditions of germaniye has a form of multilayered crystals. Layers, atom one thick, connect with each other and each layer has very changeable structure. To researchers Germany between which germanic layers atoms of calcium were located was necessary to grow up special crystals. Subsequently calcium was dissolved and removed by means of water, having left empty chemical bonds Germany. These communications then contacted atoms of hydrogen, having made structure of layers Germany is much stabler and stronger that allowed to separate their intact from the general crystal.
Now Goldberger's group plans carrying out extensive researches of all properties of the received material, Germany of one-nuclear thickness. And only after that it will be possible to start thinking of practical application german in electronic industry.
Materials about carried out by Goldberger and his team researches and their results were published in the last issue of the ACS Nano magazine.
