The group of the German scientists rotined from the Dresden research center, that a vysokolegirovannyy germanium can pass to the sverkhprovodyaschee state at atmospheric pressure. At low temperatures unalloyed semiconductors, as is generally known, gain characteristic dielectrics, and that is why for demonstration of effect to superconductivity them, obviously, it is necessary to alloy. In the examined work for alloying ions were used
gallium, which was entered in the structure of material by the method of ionic implantation. As a result the layer of admixture semiconductor was got by the thickness of 60 nm, thus on each 100 atoms of germanium in him were about 6 atoms of gallium. After completion of alloying «damaged»
the crystalline grate of semiconductor must be recovered: the surface of material is quickly (during a few milliseconds) heated for this purpose.The got semiconductor structure passes to the sverkhprovodyaschee state at a temperature about 0,5 To;
scientists, however, hope to promote this index by the change of certain parameters to ionic implantation and annealing. Speaking about dignities of new material, authors mark the unusually high value of the critical magnetic field also (maximal size
to tension at which the magnetic field does not yet get to the semiconductor) for this temperature.We will notice that germanium, used for making of firstgeneration of transistors, presently practically «forgotten» by the producers of electronics in
connections with passing to silicon. However much experts predict the revival of interest to this material, as on his basis it is possible to create more miniature charts of high fast-acting, reports "Komp’yulenta". Process of receipt of sverkhprovodyaschego
germanium by the eyes of artist. Ions of gallium (rotined blue) penetrate into material, annealing and cooling is after conducted. Kuperovskie pair (red) appear as a result, and a germanium grows into a superconductor.
