Imagine a cube on which light is projected by a flashlight. The cube reflects the light in a particular way, so simply spinning the cube or moving the flashlight makes it possible to examine each aspect and deduce information regarding its structure. Now, imagine that this cube is just a few atoms high, that the light is detectable only in infrared, and that the flashlight is a beam from a microscope. How to go about examining each of the cube’s sides? That is the question recently answered by scientists from the CNRS, l’Université Paris-Saclay, the University of Graz and Graz University of Technology (Austria) by generating the first 3D image of the structure of the infrared light near the nanocube. Their results will be published on 26 March 2021 in Science.
