Set in the Catalan Institute of Nano-technology (ICN) in Barcelona and led by Prof. Clivia Sotomayor Torres, the Phononic and Photonic Nanostructures group (P2N) investigates phonon/pho-ton/electron interactions in nano-scale condensed matter underpinned by research in nanofabrication, especially nanoimprint lithography. The long-term aim is to develop new information technology concepts where information processing is achieved with multiple state variables.
Research is carried out on nano-scale thermal and acoustic effects in both confined systems and phononic crystals; on methods to control the exciton-plasmon coupling targeting enhanced light extraction in light sources; and on the optimisation of the optical gain of printed polymer-based photonic structures.
In order to facilitate the uptake of nano-technology innovations by industry, the group is advancing nanoimprint lithography towards the realisation of 3D nano- and hybrid structures. For the latter, efforts are focused on acoustic-field assisted self-assembly of nano- and mesoscopic particles, to realise heterostructures and to deposit them selectively on patterned and or surface-functionalised substrates.

22nd April 2015. The ability of materials to conduct heat is a concept that we are all familiar with from everyday life. The modern story of thermal transport dates back to 1822 when the brilliant French physicist Jean-Baptiste Joseph Fourier published his book “Théorie analytique de la chaleur” (The Analytic Theory of Heat), which became ... more »
Dr Claudia Simão, member of the scientific committee of the 2015 E-MRS symposium on Block-copolymer self assembly for nanotechnology applications
Dr Claudia Simão was invited to join the Scientific Committee of the symposium. It will focus on block copolymer self-assembling as a tool to fabricate functional nanostructured materials. In the next coming years this area of research, at the intersection between fundamental science and technology, is expected to disclose additional insights in... more »
