Investigation of semiconductor nanostructures using optical two-dimensional Fourier-transform spectroscopy.

Investigation of semiconductor nanostructures using optical two-dimensional Fourier-transform spectroscopy.

The aim of this work is the exploration of the recently developed optical two-dimensional Fourier-transform spectroscopy (2D-FTS) method and its application in the field of semiconductor physics. The main idea of 2D-FTS is to gain information about the excited system and disentangle different contr...

Shrnutí:The aim of this work is the exploration of the recently developed optical two-dimensional Fourier-transform spectroscopy (2D-FTS) method and its application in the field of semiconductor physics. The main idea of 2D-FTS is to gain information about the excited system and disentangle different contributions to couplings within the excited many-body system. The power of the 2D-FTS method is demonstrated for an example of a semiconductor nanostructure such as quantum wells. It has been shown that by applying 2D-FTS we are able to describe the action of disorder and of the Coulomb correlations in detail.
