Energy decay in graphene resonators

Energy dissipation is a key ingredient in understanding many physical phenomena in thermodynamics, photonics, chemical reactions, nuclear fission, photon emissions, or even electronic circuits, among others.

Graphene photodetectors—thinking outside the 2-D box

In a recent work published in Nature Communications, a research group led by ICREA Professor at ICFO Frank Koppens demonstrates a novel way to detect low-energy photons using vertical heterostructures made by stacking graphene ...

High color purity 3-D printing

Selective powder sintering for 3-D printing has recently become an increasingly affordable solution for manufacturing made-to-order elements of almost any shape or geometry. This technique involves heating a bed of powder ...

Insulator-metal transition at the nanoscale

Controlling the flow of electrons within circuits is achieved through the appropriate choice of materials. Metals allow electrons to flow freely and insulators prevent conduction. In general, the electrical properties of ...
