Quantum Dot Systems

Quantum dots are artificial structures with spatial dimensions comparable to the electronic wavelength. This confinement results in a 0D discrete energy spectrum. Due to the similarity of such spectra to spectra of natural atoms, quantum dots are also called “artificial atoms”. By coupling several quantum dots, “artificial molecules” are created. These platforms are subject to intensive basic research due to their potential applications in quantum information processing.

The focus of our group lies on the examination of electron properties of quantum dot systems which are defined by lithographically on two-dimensional electron gases and on self-organized InAs quantum dots.
