the Siberian scientists will create laboratory of growth of semiconductors on MKS
Novosibirsk, 28 okt - News, Maria Rogovaja. WRK on manufacturing and test of pilot installation 4 synthesis semi-conductor nanostruktur " the Screen - M " which will take place onboard MKS, have begun at Institute of physics of semiconductors (IFP) the Siberian Branch of the Russian Academy of Science, the deputy director on scientific WRK of institute, the head of this project, professor Oleg Pcheljakov has informed on Friday of News.
In semi-conductor electronics use crystal mately which grow up in the conditions of deep vacuum. Uniformity of the RCVed crystals which gives the chance to change and supervise their spending properties by means of impurity brought further (legirovanija) depends on cleanliness semi-conductor matelov.
According to Pcheljakova, synthesis qualitative semi-conductor matelov on the Earth demands installations which cost millions dollars and considerably concede on cleanliness of vacuum to a natural space.
" the project Purpose - creation of minifactory 4 manufacture new semi-conductor matelov in an orbit. The kilvaternyj trace for attached to a spaceship board the molecular screen is an area of superdeep vacuum and the ideal environment 4 growth of semi-conductor crystals, original vacuum laboratory. Separate molecules of the rarefied gas do not get to it, not to mention oxygen and other elements which absence guarantees quality of a growing film of the semiconductor " EVN; - Pcheljakov has told.
the Scientist has explained that pressure of atmosphere in space vacuum laboratory in 100 times more low, than in the best land vacuum chambers. Besides, behind the filter there is no cover of walls - the basic source of pollution - and special cooling is not required. It will allow to make semi-conductor structures 4 nanoelektroniki and nanofotoniki, in particular, photo cells of solar batteries on the basis of silicon from EFFICIENCY more than 30 % against existing 15 %.
WRK on creation " the Screen - M " are conducted together with it is rocket - space corporation " Energy " of S. P.Koroleva.
According to the interlocutor of the agency, the first successful tests of samples folg of which it was planned to make the molecular screen - protective holodostojky and strong " an umbrella " in diameter about three metres W a covering preventing accumulation of a static charge and evaporation from its surface - have taken place at the international station " the World " in 1998. After deluging of station project financing has stopped at a stage of creation of land vacuum installation " Epicentre " - the simulator of space vacuum.
Some years of WRK on the project proceeded in IFP the Siberian Branch of the Russian Academy of Science at the expense of own means. Then financing has renewed, and all spadework has been executed.
In October the Institute of physics of semiconductors of the Siberian Branch of the Russian Academy of Science has RCVed the first transfers from RKK " Energy " on the third stage (" the Screen - 3 ") Including directly creation of installation which will go into an orbit. The total cost of the project will make about 2 billion roubles, the project head has informed.
the Expert has specified that IFP the Siberian Branch of the Russian Academy of Science together with Experimental plant of the Siberian Branch of the Russian Academy of Science and NPF " elektron " (Krasnoyarsk) will create three samples of installation " Epicentre " - one 4 WRK in the CTR of preparation of cosmonauts of Ju.A.Gagarin, the second - 4 bench land tests W maximum loads and third - it is direct 4 the organisation of pilot laboratory in an orbit.
He has added that in case of successful end of WRK the project recoupment will make about four - five years.
