"Continuing the pattern of halving the surface area of each node (or reducing the square sides by 1.4) every two years, it can be expected that 4 nm technology will appear in roughly 2022, 3 nm in 2024, 2 nm in 2026, and lastly 1 nm in 2028, which may be the limit for current lithographic semiconductor silicon technology as presently implemented. As a result 2030 and beyond may see a shift in technology to enable smaller components in the form of silicene or silicon nanotubes or a move towards other processing methods such as quantum computing.
Transistors one atom thick and ten atoms wide have been made by UK researchers. They were carved from graphene, predicted by some to one day oust silicon as the basis of future computing. Graphene is a material made from flat sheets of carbon in a honeycomb arrangement, and is a leading contender. A team at the University of Manchester, UK, have now used it to make some of the smallest transistors ever. Devices only 1 nm across that contain just a few carbon rings."
Tehat 2030 utan mar gondok lesznek, de addigra talan sikerul hasznalhato optikai rendszereket is kesziteni, ami azt jelenti, hogy onnantol egy atom helyett 1 foton lesz a legkisebb keresztmetszet.
