Phonon-electron coupling in twisted 2D layers under mechanical strain:

This project will study the phonon and exciton dynamics in CVD-grown, semiconducting single layer MoS2 and bilayers with twisted angles on flexible and stretchable substrates. Non-destructive optical techniques such as high resolution Raman spectroscopy, photoluminescence and ultrafast pump-probe will be applied in order to fully understand the strain-enabled phonon-electron interactions.

Cooling Photonics on stage at Expoquimia 2021


cooling photonics.jpg

Cooling Photonics, is a spin-off company of ICN2 from the P2N group that provides passive cooling solutions without energy consumption or carbon emissions. The technology pushed forward by the company consist of a nano-fabricated coating material that can be applied on any surface hotter than the ambient, allowing the dissipation of heat as infrared radiation and, thus, decreasing its temperature.
The research activities that resulted in the creation of the company were mainly coordinated by senior researcher Dr. Juliana Jaramillo Fernández. Javier Achiaga, CEO of Cooling Photonics, Antonio Cuenca, COO, and Dr. Juliana Jaramillo presented the company, the technology and its applications in a talk at Expoquimia 2021.

Novel high-sensitivity and fast response magnetometer



Optomechanical cavities are devices able to amplify interactions between light and mechanical systems, which are used as very sensitive detectors of displacement. Thanks to the interaction of magnetic fields with mechanical elements, optomechanical devices can also serve to measure magnetic field, i.e. as magnetometers. In particular, the ability to measure small fields over a broad range of frequencies is relevant to many applications in geology, space exploration, biology and medical imaging.

PHENOMEN (H2020 FET OPEN project) assessed as excellent by the European Commission

August 06, 2020

The EU Project PHENOMEN (All-Phononic circuits Enabled by Opto-Mechanics), a H2020 FET OPEN funded project coordinated by the ICN2-P2N was evaluated as excellent by the European Commission. The consortium proved convincingly the feasibility of a phononic circuit working at room temperature using silicon compatible technologies. Here some excerpts from the evaluation report.

“The reviewers unanimously agree the project has delivered “exceptional results with significant immediate or potential impact”.
We confirm that the outcome from the project, in terms of new understanding in physics of phonons and their possible outcomes definitively will influence the research community. The project has delivered several important results, both in terms of models and simulation tools development as in terms of new technology.”

New MSCA-IF-2019 - Individual Fellowships Postdoc

June 10, 2020

Congratulation to Dr. Ryan Cecil Ng for being awarded with this prestigious fellowship. During this project, we will explore novel designs for optomechanical nanostructures and develop experimental methods to address the phononic and photonic modes of nanoscale objects from free-space. Using embedded light emitting quantum dots we will avoid the limitations imposed by optical fibers currently used to bring light to the optomechanical cavity, which will in turn enable the incorporation of optically active materials in mechanical resonators and prepare them for up-scaling.

Self-assembled microspheres article mentioned in local news

November 21, 2019

Our recent published article: "A Self‐Assembled 2D Thermofunctional Material for Radiative Cooling" authored By J. Jaramillo-Fernandez has been recognized by several Spanish newspapers as scientific breakthrough in thermal management. Renowned newspaper as La Vanguardia and La Razón highlighted our research in their pages. In addition a local  TV channel (TV3) mentioned in its webpage. It is important to remark that the importance of  this kind of technologies has not gone unnoticed. Part of our team (J Jaramillo-Fernandez, A. Francone and N. Kehagias) have also developed another material that is easily up-scalable and is capable of providing both radiative cooling and self-cleaning. The Collider, a technology transfer program promoted by Mobile World Capital Barcelona that connects scientific research with entrepreneurial initiative, has awarded this project The Collider Tech Award 2019, a prize that encourages further development of this research line on radiative cooling materials. A European patent protecting the intellectual property rights of this technology was filed on 31 July 2019 by the ICN2 and ICREA.
