Optics Near Surfaces and at the Nanometer Scale

Gearing up nanoscale machines

Molecular gears are ultimate miniaturization of gears. In order to follow the rotation of successive cogwheels and the transmission of a rotational force along a train of molecular gears, chemical labelling was achieved to induce local contrast on STM images and differentiate one single paddle among the five.

A red star is born

Large starphenes can be accessed by thermal decarbonylation in the solid state, on a surface in ultra-vacuum of tricarbonylated precursors
