Physicist Kin Yap Yoke from Michigan Technological University, offered his alternative to silicon transistors . He came up with the idea to place the quantum dots on the insulating substrate, and the current at sufficient voltage to move between points, due to the effect of tunneling. This is not a new idea, but such a system where only operate at low temperatures, which is not allowed to consider them as a complete replacement for transistor.
Professor Yap has solved this problem by placing a gold quantum dots of about 3 nm on a substrate of nanotubes based on boron nitride. According to the description , the electrons with incredible accuracy jumped from one point to another. An additional feature of the development is the absence of leakage current in the form of heat dissipation, as it does not apply semiconductors. The size of the obtained transistor is about 1 micron to 20 nanometers wide, and currently it is made a patent application. Related Products :
