Femtosecond Probing of Photoinduced Refractive Index Changes in Semiconductors,e been reached and scientists are exploring new technologies for transmitting, storing and processing information. Many believe that light or photons will form the new “current” for information in the next century and that photonics could possibly supplant electronics in several devices. Certainly p

Tunneling of Electrons and Holes in Asymmetric Double Quantum Wells,n particular asymmetric double quantum well structures (a-DQWS), provide ideal systems for investigating tunneling phenomena, especially when an electric field is applied to bring various electronic levels into resonance. We first discuss various resonant and nonresonant tunneling processes for elec

Relaxation of Frenkel-Type Rotational and Vibrational Excitons in Diatomic Molecular Crystals,d the corresponding techniques for time-resolved optical measurements. Nowadays, infrared-as well as Raman-active transitions can be interrogated with shorter than picosecond (1 ps = 10. s) time-resolution using, e.g., infrared absorption saturation and transient hole-burning spectroscopy

Quantum Transient Transport,e basic point of view, this phenomenon has received large interest, since it allows the analysis of many fundamental aspects of solid-state physics, such as electron states, both localized and extended, surface and interface structures, electron-phonon interactions, impact ionization, etc. These two

Tunneling of Electrons and Holes in Asymmetric Double Quantum Wells,t tunneling rates of electrons and holes in asymmetric double quantum well structures using time resolved spectroscopy. We also show that cw and ultrashort pulse experiments probe different physics and that it is difficult to obtain quantitative information about resonances and resonant tunneling rates from cw experiments.
