Publikováno v: St. Petersburg Polytechnical University Journal: Physics and Mathematics, Vol 16, Iss 3 (2023)

In the paper, a possibility of increasing the terahertz (THz) radiation intensity under optical interband pumping in the epitaxial GaAs layer doped with shallow donors has been studied. An increase in the intensity of THz radiation was achieved by im

The existence of localized structures, including so-called cavity solitons, in driven optical systems is discussed. In theory, they should exist only below the threshold of a subcritical modulational instability, but in experiment they often appear s

Engineering of Semiconductor Heterostructures by Ultrathin Control Layers

Autor: Raffaele Resta, Alfonso Baldereschi, Stefano Baroni, Kurt A. Mäder, Maria Peressi

Publikováno v: Semiconductor Interfaces at the Sub-Nanometer Scale ISBN: 9789401049009

We review in this paper the electronic properties of semiconductor heterojunctions. We focus on interface-specific phenomena, where the conditions of growth—including controlled contamination—may significantly alter the physical properties of the
