"Positively charged holes in semiconductor nanostructures" with Prof. Alex Hamilton

Today your PC contains over 10 billion transistors – and half of these use holes, not electrons, to operate. These transistors are already being manufactured with feature sizes down to 22 nanometres! This talk will look at the differences between electrons and holes in extremely high quality nanoscale devices, operated at low temperatures where quantum effects are dominant, to illustrate some of the rather large gaps in our knowledge.
