High-resolution STM imaging of molecular structures with functionalized tips

We have been the first to resolve the inner structure of an organic molecule using scanning tunneling microscopy (STM) tips funcitonalized with molecular hydrogen [1,2,3]. Later we have shown that high resolution is routinely achieved when STM tips are funcitonalized by an atom or a small molecule [4]. Together with the team of NanosurfLab we identified the mechanism responsible for the appearance of high resolution in scanning probe microscopy (SPM) with funcitonalized tips [5,6]. High-resolution STM imaging of molecular structures with funcitonalized tips helped us to establish a concept of nanoscale sensor-transducer [7]. Exploiting this concept further we have recently succeeded in fabrication of a new type of single-moleucle device that is sensitive to changes of electrostatic potential.
