Key properties of quantum materials stem from dynamic interaction chains that connect
stable electronic quasiparticles through short-lived coherences, which are difficult to control …

Because of the strong spatial confinement of electronic wave functions and reduced
dielectric screening, the effects of carrier-carrier Coulomb interactions are greatly enhanced …

Hydrogen sensors and hydrogen-activated switches were fabricated from arrays of
mesoscopic palladium wires. These palladium “mesowire” arrays were prepared by …

Transient nonlinear optical spectroscopy, performed on excitons confined to single GaAs
quantum dots, shows oscillations that are analogous to Rabi oscillations in two-level atomic …

Instabilities in semiconductor heterostructure growth can be exploited for the self-organized
formation of nanostructures, allowing for carrier confinement in all three spatial dimensions …

A review is given on the formation mechanisms and the properties of Si/Ge nanostructures
that have been synthesized by self-assembling and self-ordering during heteroepitaxy …

The result of a lecture series, this textbook is oriented towards students and newcomers to
the field and discusses theoretical foundations as well as experimental realizations in detail …

We investigated the manifestation of Rabi oscillation in the coherent dynamics of excitons in
self-assembled semiconductor quantum dots. The Rabi oscillation phenomenon was directly …

We report on the coherent optical excitation of electron spin polarization in the ground state
of charged GaAs quantum dots via an intermediate charged exciton (trion) state. Coherent …

The use of ultrafast gating techniques allows us to resolve both spectrally and temporally the
emission from short-lived neutral and negatively charged biexcitons in ultrasmall (sub-10 …
