3D rendered image showing a heated nanoscale silicon tip, borrowed from atomic force microscopy that is chiselling away material from a substrate to create a nanoscale 3D map of the world.
As reported in the scientific journal Advanced Materials, IBM Researchers used this new nanopatterning technique to create the smallest map of the world in 3D, measuring only 22 by 11 micrometers was “written” – on a polymer - at this size 1000 world maps could fit on a grain of salt. In the relief, one thousand meters of altitude correspond to roughly eight nanometers (nm). It is composed of 500,000 pixels, each measuring 20 nm2 and was created in only 2 minutes and 23 seconds.
