Abstract
An atomic-force microscope, operating at low temperatures, can be used to create and tailor quantum electronic devices, and could provide a means of building the intricate circuits needed for quantum computing.
It is 30 years since the appearance of the first semiconductor electronic devices built to make use of the effects of controllable quantum confinement of electrons. These 'resonant tunnelling diodes'1 trapped charges in only one dimension.
