Recent investigations of excitonic absorption spectra in cuprous oxide (Cu 2 O) have shown
that it is indispensable to account for the complex valence-band structure in the theory of …

Excitons are the elementary excitations of the electronic system of a semiconductor and,
hence, fundamental quasi-particles in solid state theory. Consisting of a negatively charged …

In solid state systems it is possible to excite electrons from the valence to the conduction
band. Instead of treating the interaction of the excited electron with the remaining electrons …

Excitons are fundamental electronic excitations in a semiconductor. They are bound states
consisting of an electron in the conduction band and a positively charged hole in the …

Exzitonen in äußeren Feldern sind ein wertvolles Modellsystem, um theoretische
Vorhersagen über eine Vielzahl verschiedener Effekte experimentell zugänglich zu machen …
