NanotechnologyTimes – Silicon-based microelectronic devices have revolutionized our world over the past 30 years.
Integrated circuits, built from silicon devices such as transistors and diodes on a single chip control everything from cars to telephones and even the Internet.
Moore’s Law that says computer power doubles every 2 years has been true for nearly 50 years. But that will finally come to an end by 2020.
After 2020, it will be impossible to miniaturize further and to place double the number of transistors on a silicon chip. Computer chips continue to shrink but the discovery that a layer of silicon dioxide must be at least four to five atoms thick to function as an insulator suggests that silicon-based microchips will reach the physical limits of miniaturization by 2020. At the time when silicon will reach to its end, carbon nanotubes will take over its place. This is another example how nanotechnology is going to impact our life in the future.
