Surface electromagnetic fields mapped in 3D at the nanoscale

Presse/Medien: Presse / Medien

Beschreibung

The first three-dimensional map of the electromagnetic field that “clings” to the surface of a cube less than 200 nm across casts a fresh light on how materials dissipate heat at the nanoscale. The images, obtained by researchers in France and Austria, reveal the presence of infrared photon-like excitations known as surface phonon polaritons near the cube’s surface – a phenomenon that might be exploited to convey waste heat away from nanoelectronic components and so cool them down.
