We introduce an ultrathin donor-acceptor solar cell composed entirely of inorganic nanocrystals spin-cast from solution. These devices are stable in air, and post-fabrication processing allows for power conversion efficiencies approaching 3% in initi

Combining linear polarization excitation and magnetic-field breaking of chiral symmetry of optical transitions in Group-III-V semiconductors, we use resonant degenerate four-wave mixing to observe effects beyond the time-dependent Hartree-Fock theory

In recent years, the search to develop large-area solar cells at low cost has led to research on photovoltaic (PV) systems based on nanocomposites containing conjugated polymers. These composite films can be synthesized and processed at lower costs a

Polarization dependence of four-wave mixing in bulk GaAs

Autor: Daniel S. Chemla, W. Schaefer, Peter Kner, N. A. Fromer

Publikováno v: Technical Digest. Summaries of Papers Presented at the Quantum Electronics and Laser Science Conference.

Summary form only given. Coulomb correlation between excitons created by co-circular polarization, /spl sigma//sup -///spl sigma//sup -/, have been extensively investigated. Here we compare four-wave mixing (FWM) experiments performed with linear pol

Coulomb correlations in a two-dimensional electron gas in large magnetic fields

Autor: C. W. Lai, D. D. Driscoll, A. C. Gossard, Ilias E. Perakis, Daniel S. Chemla, N. A. Fromer, Christian Schüller

Publikováno v: Physical Review B. 66

We present an investigation of the dynamics of the inter-Landau-level (LL) excitations of a two-dimensional electron gas (2DEG) in large magnetic fields using coherent time-resolved nonlinear spectroscopy. The results are compared directly with measu
