Postdoctoral position in population detected 2 dimensional electronic spectroscopy of energy materials

ICFO is offering a postdoctoral position to a well-qualified, highly motivated and dynamic young scientist who wishes to enhance his career.

The successful candidate will be joining the Molecular Nanophotonics group led by Prof. Dr. Niek van Hulst to participate in the Population detected 2 dimensional electronic spectroscopy project, addressing the following tasks:
1. Sampling local ultrafast multidimensional spectra. Setting-up 2-dimensional (excitation-emission) spectroscopic microscopy to map the development of the energy landscape, identify the excited state couplings, and elucidate the role of spectral and spatial disorder. Implementing population sensitive collinear 2D spectroscopy with both photocurrent and emission detection, to allow spatial 2D-spectrocopy on organic and semiconductor energy materials, and operando on operating solar cells.
2. Tracking energy transport on the nanoscale: tracking spatiotemporal transport by super-resolved transient optical microscopy, nanophotonic light localization and point-to-point collinear 2D spectroscopic imaging: to reveal spatial disorder and quantify diffusion.
3. Reduced sampling Time-Domain Spectroscopy, i.e. or Spectroscopy on a Budget. Nanoscale nonlinear spectroscopy is very low on SNR and requires long acquisition times. Goal is to rationalize the possible advantages of a smart sampling scheme tailored to the experiment characteristics and/or the expected results. Next demonstrate how a smart sampling reduces the acquisition time of an experiment while still providing a similar level of information.
