It’s not an official Guinness World Record…yet, but researchers at the Technical University of Denmark (DTU) claim to have created the world’s smallest record. Measuring just 40 microns in diameter, it includes the first 25-seconds of the iconic Christmas tune ‘Rocking Around the Christmas Tree’.
This was achieved using an all-new nano-sculpting machine, called the Nanofrazor, which was recently acquired from Heidelberg Instruments. The Nanofrazor is capable of engraving 3D patterns into surfaces with nanoscale resolution, thus enabling the researchers to create new nanostructures that may pave the way for novel technologies in fields such as quantum devices, magnetic sensors and electron optics.

We work with 2D materials, and when these ultrathin materials are carefully laid down on the 3D landscapes, they follow the contours of the surface. In short, they curve, and that is a powerful and entirely new way of “programming” materials to do things that no one would believe were possible just fifteen years ago. For instance, when curved in just the right way, graphene behaves as if there is a giant magnetic field when there is, in fact, none. And we can curve it just the right way with the Nanofrazor,” said Peter Bøggild, Section Manager at the Technical University of Denmark (DTU).
