Sažetak

What makes three dimensional semiconductor
quantum nanostructures so attractive is the possibility to
tune their electronic properties by careful design of their
size and composition. These parameters set the
confinement potential of electrons and holes, thus
determining the electronic and optical properties of the
nanostructure. An often overlooked parameter, which has
an even more relevant effect on the electronic properties
of the nanostructure, is shape. Gaining a strong control
over the electronic properties via shape tuning is the key
to access subtle electronic design possibilities. The Pulsed
Dropled Epitaxy is an innovative growth method for the
fabrication of quantum nanostructures with highly
designable shapes and complex morphologies. With
Pulsed Dropled Epitaxy it is possible to combine different
nanostructures, namely quantum dots, quantum rings
and quantum disks, with tunable sizes and densities, into
a single multi‐function nanostructure, thus allowing an
unprecedented control over electronic properties.
