Time-resolved reflectivity technique: improvement and applications

Theory of carrier dynamics and time resolved reflectivity in InxMn1−xAs/GaSb heterostructures

We present detailed theoretical calculations of two color, time-resolved pump-probe differential reflectivity measurements. The experiments modeled were performed on InxMn1−xAs/GaSb heterostructures and have shown pronounced oscillations in the differential reflectivity as well as a time-dependent background signal. Previously, we showed that the oscillations resulted from a generation of coher...

Membranes at interfaces: structure studies by AFM and time-resolved neutron reflectivity.

Model biomembranes are either organized as vesicles or as planar bilayers. These represent two principally different model systems for the investigation of biophysical processes in single bilayers. Here we report on supported planar layers prepared by precipitation of lipid molecules from vesicles in a suspension [1], and on initial studies of small peptides interacting with such model membrane...

Nanosecond time-resolved reflectivity determination of the melting of metals upon pulsed laser annealing

Thin metal fiIrns (Cu, Au, Ni) on quartz glass were illuminated with nanosecond pulse.; of a frequency doubled Nd:YAG laser (A = 532 nm). The transient reflectivity behavlour was probed at the wavelength 633 nm, where these metals exhibit Drude-Iike optical behaviour: the reflectivity decreases with temperature in the solid and in the Iiquid state as well as at the solid-llquid phase transition...

Time-Resolved Fluorescence of Lanthanide Probes and Applications in Biotechnology

Passive time-multiplexing super-resolved technique for axially moving targets.

In this paper we present a super-resolving approach for detecting an axially moving target that is based upon a time-multiplexing concept and that overcomes the diffraction limit set by the optics of an imaging camera by a priori knowledge of the high-resolution background in front of which the target is moving. As the movement trajectory is axial, the approach can be applied to targets that ar...
