We describe recent continuous wave studies of stimulated polariton scattering in semiconductor microcavities, with emphasis on the variety of new physics which has been observed in the last few years. The ability to manipulate both exciton and photon prope ...
Recently, it was shown that semiconductor-metal hybrid structures can exhibit a very large magnetoresistance effect, the so-called extraordinary magnetoresistance (EMR) effect. This led to the perspective of using EMR devices in magnetic-field sensors and ...
Nucleation and growth models are well developed for nucleation on homogeneous substrates, and they can typically be described-in terms of three energy parameters. Nucleation on substrates containing point-defect traps has been investigated, at the cost of ...
A new series of iridium(III) mixed ligand complexes TBA[Ir(ppy)2(CN)2] (1), TBA[Ir(ppy)2(NCS)2] (2), TBA[Ir(ppy)2(NCO)2] (3), and [Ir(ppy)2(acac) (4) (ppy = 2-phenylpyridine; acac ...
Organic light emitting devices (OLED) are among the most promising future technologies for the manufacture of flat and inexpensive displays. Although OLEDs provide already much higher brightness as compared to liquid crystals devices (LCD), they have a maj ...
Beam distortion profiles are studied for scanning devices that have a single mirror with two rotational degrees of freedom (DOF), also named tip/tilt scanners. The case of a fast steering scanner used for high power material processing applications is stud ...
This paper describes recent work on high-occupancy effects in semiconductor microcavities, with emphasis on the variety of new physics and the potential for applications that has been demonstrated recently. It is shown that the ability to manipulate both e ...

The invention concerns a electroluminescent device with a multilayer structure comprising: i) a first electrode including a layer, consisting of a transparent or translucent conductive material selected among metal oxides and metal nitrides, said layer bei ...
We discuss a detailed near-field spectroscopic study of the nanoscopic optical properties of a novel coupled wire-dot nanostructure grown on (31 1)A GaAs substrates. Photoluminescence spectra recorded with 150 mn spatial and 100 mueV spectral resolution pe ...
We investigate the interaction of Ti atoms with thin films made of 3,4,9,10 perylenetetracarboxylic dianhydride (PTCDA) molecules by means of self-consistent electronic structure calculations within a generalized gradient approximated density-functional th ...
