IBM researchers recently demonstrated graphene-based transistor, which shows incredible cut-off frequency.
      
      Graphene is a special form of carbon, which was first demonstrated in 2004 by physicists from University of Manchester, Great Britain, and Institute for Microelectronics Technology, Russia. This two-dimensional material has unique electric, optical, mechanical and thermal properties, which allowed regarding it as a serious candidate for post-silicone microelectronics.
      
      Researchers form IBM corporation developed a graphene-based nano-sized transistor, which works with cut-off frequency of 100 billion work cycles per second. Never before graphene semiconductors demonstrated such high frequencies.
      
      Uniform and high-quality graphene plates were made by means of thermal decomposition of silicon carbide.
