Fields of Interest

 

Transport properties of low-dimensional electron gases embedded in free-standing nanostructures.

Freely suspended nanostructures with a thickness of the order of only 100 nm only permit a discrete set of lattice vibrations in the confined direction and are therefore also referred to as phonon cavities. The phonon spectrum of such a cavity is characterized by quantized subbands as well as the occurrence of so-called cavity modes. This allows to tailor the electron-phonon coupling and thus phonon-mediated dephasing processes. The interaction of single electrons with individual cavity phonon modes is investigated in free-standing quantum dots (electron-phonon cavity) revealing interesting transport properties.
