Australian National University - Research School of Physical Sciences and Engineering - Nanotechnology and Mesoscale Physics at RSPhysSE

Nanotechnology (the science of the very small) and mesoscale (systems of the order of milimeters in size) research at RSPhysSE includes:

Quantum wells wires and dots. Quantum wells are formed by building up atomically thin layers on the surface of semiconductor wafers using MOCVD. The extremely small scale of these structures means that their properties are influenced by quantum effects and this can be used to technological advantage by for example engineering the confinement of carriers within semiconductor laser structures. Wires are atomically thin in two dimensions and dots, in three. Quantum dots can be grown by MOCVD by careful choice of growth conditions and post growth annealing. mismatches in the lattice between grown layers being used to "condense" drops on the wafer surface.
