British researchers have unearthed the world's smallest transistor, measure one atom thick and ten atoms crossways.
An global team has argue that despite its very small size - only four billionths of a meter long - quantum dot is a practical electronic unit, the world's first intentionally created by placing every particle.
According to the researchers that can be used to control and control the electrical current flows as a profitable transistor, but it is a decisive step into a new era of atomic-scale smallness and super-fast computer.
"The meaning of this result is that we not only move the atom around, or look at them from side to side a microscope. We influence individual atoms and place them with atomic precision, to create a useful electronic device.
"The team has been able to create an electronic device right out of crystalline silicon, where we have replaced only seven person silicon atoms to phosphorus atoms. It's amazing correctness.
"This is a great technical achievement, and it is a decisive step to show that it is possible to build the ultimate machine - a quantum computer in silicon," team associate.
