Özet:

 

How small can an electronic device be and still function?   How many atoms are needed for such device? At what point will the   semiconductor fabrication technology be unable to construct anything   smaller? These are common questions asked by researchers, and the answers   indicate the short-term limitations on the use of semiconductor technology.   When we reach these limitations, we can propose two methods to solve these   problems: first, we could continue using semiconductor technology, alongside   the development of new theories and techniques to counter quantum effects   caused by the miniaturization of electronic devices like transistors and   microprocessors. Second, we could exploit these quantum effects to invent a   new generation of electronic devices. Doing that, we propose spintronics or   the use of spin properties. Heusler compounds as cobalt base alloys   (Co22_{2}YZ) present particular interest for spin electronics applications.   In this paper, we present properties and results for two cobalt base alloys,   Co22_{2}FeGa and Co22_{2}FeSi. These properties are interesting for the   field of quantum computation. In the first part of this paper we introduce   Moore's law, which explains the major limits of semiconductor technology.   Then we discuss the results of our calculations based on the use of density   functional theory and the WIEN2K program. This is for the purpose of making   new quantum devices.
