Computer chips can reach speeds of 3,000GHz

A new design could help chips not only reach 3-terahertz speeds - equivalent to 3,000GHz - but also produce very little heat that has just been announced.

This computer microprocessor design was named Ballistic Deflection Transistor (BDT) and was the result of researchers at Rochester University.

Marc Feldman - Professor of computers at Rochester University - affirmed that BDT design will be the basic foundation. The BDT design has no capacitance layer like the transistor designs used in current chips. Capacitive layer is the factor causing the most difficult problems when the chips are getting smaller and smaller.

The principle of operation of BDT design is to use inertia instead of using a large energy source to force the electrons to go into their chosen orbit. The BDT design only performs the function of an intersection of electrons rather than a device that generates energy to start and stop the operation of electrons. This is the solution that will help save energy in the new chip design.

All BDT designs come in a semiconductor layer called "2D electron gas". This material plays a role in supporting the movement of electrons, preventing them from being affected by impurities.

Feldman said he hopes the BDT design will produce very little heat. " We do not have the correct algorithm to calculate and estimate how much heat this design can produce. But according to what we know now, this design will only produce very little. The heat and energy used will be very small . "

The first version of the BDT chip design only produced about a few microwatt (1 microwatt = 1 millionth of a watt) calculated on each transistor. This will be a very effective heat reduction and energy consumption solution for chips. However, this is still a matter of the future because this design is still at the idea level.

The US National Science Association has granted the University of Rochester a US $ 1.1 million budget to produce the transistor design and chip version according to the design.
