Research

Methods for the observation and characterization of individual nano-objects.
Super resolution microscopy for the observation and chemical characterization of nano-objects and nanostructures. Special emphasis on label-free methods avoiding the labeling of the objects with fluorescent dyes. The methods are well tailored for nano-material research. We are making use of photo-induces thermal profiling to enhance resolution.
Development of methods to measure light absorption and light extinction in individual nano-objects and nanoparticles.
Characterization nanoparticles in the search for direct band gap photovoltaic materials. The major focus is on finding Ge/Si core multi-shells nanowires with enhanced photovoltaic yields in the infrared.
