Photocurrent measurements have been performed on a quantum cascade detector structure under strong magnetic field B applied parallel to the growth axis.

We observe microwave-induced photocurrent and photovoltage oscillations around zero as a function of the applied magnetic field in high mobility GaAs 2D electron systems.

We report the observation of self-sustained photocurrent oscillations in a weakly coupled spatially direct intrinsic GaAs/Al0.3Ga0.7As superlattice.

The kinetics of photochemical transformation of a ``yellow{''} deprotonated form (M -> O transition) in bacteriorhodopsin mutants without primary proton acceptor D85 (D85N, D85N/D96N, D85T/E204Q

Carbon images were prepared by the thermal decomposition of photodefined novalac resist (HPR-206) patterns.

By freezing CO-bound cytochrome c- oxidase at cryogenic temperatures, we have been able to cryotrap metastable intermediates.

Mass resolved carbon cluster cations from C sub 3 sup + to C sub 20 sup + have been photofragmented using 248 nm and 351 nm light.

Dissociation energies and optical absorption spectra of metal clusters have been measured by photodissociating them with a tunable dye laser.

High stresses developed within plastic encapsulated microelectronic devices can compromise device reliability.

The photoelastic effect, or strain dependence of refractive index n(o), essentially controls the details of light scattering in liquids, glasses and crystals.
