For more than 10 years, an invisible race has been going on between specialists in the field of microelectronics to create the smallest transistor. At the moment, the threshold for the size of the gate of the transistor (the electrode to which the control voltage is applied) was considered to be 5 nanometers.
A US Department of Energy National Laboratory research team led by Professor Ali Jawi has developed a 1nm gate transistor. In comparison, a strand of human hair is 50, 000 nm thick. To create it, carbon tubes and molybdenum disulfide, better known as a component of lubricants for automobile engines, were used.
Despite the outstanding result, Professor Ali Jawi is convinced that he and his colleagues are only at the beginning of the journey:
“Yes, we managed to create the smallest transistor to date. However, this is just a proof of concept. We have not yet migrated these transistors to the chip, nor have we created an equalization circuit to reduce parasitic resistances in the device. However, we have proven that it is possible to go beyond the 5nm gate. Moore's Law will continue to operate for some time due to the correct design of the architecture of the semiconductor material. "
The development of scientists will help "stay afloat" Moore's Law (Gordon Moore is one of the founders of Intel), which states that the density of transistors in integrated circuits will double every two years, thereby opening up opportunities to increase the performance of electronic devices.
