The group has employed molecular beam epitaxy to create first a quantum dot structure made of InAs (indiaum arsenide)/GaAs (gallium arsenide) and then a metal mask with a 0.
A low density of InGaAs quantum dots (QDs), semiconductor nanostructures with 10 nm to 20 nm dimensions, is grown on GaAs by molecular beam epitaxy.
By using an atom-deposition technique called molecular-beam epitaxy and by exploiting a tendency of indium atoms to bunch together, the researchers covered an entire chip with triangular arrays of exactly six indium atoms per patch of silicon 3 nm on a side.
