Our research in brief
Things change at the nanoscale! New phenomena arise, making nanoscale objects behave differently than macroscale objects. These new phenomena can be used in a plethora of novel applications and devices, which explains the great hope in nanoscience to provide entirely new technologies rather than only a way to make things smaller.
The colour of gold nanoparticles forms an excellent example of a nanophysical phenomenon. In contrast to large gold objects, gold nanoparticles are red and shiny. This is due an extraordinary strong interaction between light and metallic nanostructures. Light of certain colours is scattered and absorbed by the structure through excitation of collective electron oscillations, known as plasmons. Through plasmonic excitations, these structures offer means to manipulate light at the nanoscale. They can focus light to nanoscale hot spots or act as light-triggered nanoscale heat sources.
In our research we utilize unique optical properties of plasmonic metal nanostructures in conceptually new applications. In particular, we explore hybrid plasmonic devices where we combine plasmonic systems with different organic thin films., such as conducting polymers. By bridging the fields of nanoplasmonics and organic electronics, we aim to provide novel concepts for energy harvesting, sensing and displays. Related areas of interest include nanofabrication, organic electronic devices, photoconductive materials, and thermoelectrics.
