Indium tin oxide (ITO), Au and Pt are materials of interest as high work function contacts for organic semiconductor devices. In this paper the relative energy level line-up of these materials is investigated both as bare surfaces or part of a polyme

Evanescent coupling is used to couple light from an organic Lambertian emitter into a single-mode planar waveguide. A polymer light emitting diode pumps a photoluminescent layer located directly on top of the waveguide. At the out-coupling grating st

Organic semiconductors hold the promise for large-area, low-cost image sensors and monolithically integrated photonic microsystems. This requires the availability of photodiodes offering at the same time high quantum efficiency, low noise and long li

An optical touch and proximity sensor based on polymer light-emitting diodes and polymer photodiodes is presented. The sensor’s thin-film light sources and detectors are monolithically integrated in the same plane of a common substrate and are proc

a ´´ Abstract We discuss a novel approach to measure the electron phase-relaxation length and femtosecond lifetimes at surfaces. It relies on the study of the spatial decay of quantum interference patterns in the local density of states (LDOS) with

We have used the Pt(997) surface as a deposition template to grow high-density arrays (5×106 cm−1) of parallel Co nanowires. We demonstrate that we can routinely grow ordered arrays of single monatomic chains of Co with precise coverage monitoring

Dispersion relations of the s–p derived surface state on (111) surfaces of silver and copper have been measured using low-temperature scanning tunneling microscopy and spectroscopy. For silver as well as for copper we find a significant deviation f
