NaioSTM - All-in-One Scanning Tunneling Microscope

Gerd Binnig and Heinrich Rohrer of the IBM Research Laboratory in Rüschlikon, Switzerland, constructed the first scanning tunneling microscope (STM) in 1981, making individual atoms clearly visible to a select number of specialists for the first time. In 1986, they were awarded the Nobel Prize in Physics. Nanosurf took it a step further in 1997, bringing single atoms into the classroom!

The NaioSTM is a scanning tunneling microscope that combines the scan head and controller into a single instrument for much easier installation, operation and transportability. The system is vibration-resistant and may be utilized in regular classroom settings to attain atomic resolution on HOPG. With a footprint of 204 × 204 mm, it takes up very minimal space.

  • Atomic resolution in 5 minutes
  • Tiny footprint, easy to store and transport
  • Small mechanical loop offers outstanding stability


Smart Design

The system includes a scan head, controller, air-flow shielding with a magnifying glass to facilitate the first approach and vibration isolation on a huge stone table, which is well-suited to the demands of educational institutions. 

On a coffee table or in a classroom, the very small mechanical loop of <10 mm offers the stability needed to reach atomic resolution. The extra passive vibration isolation feet further protect measurements from disruptions, resulting in a very robust system when in use. The system does not require high voltage to operate, making it safe in the hands of untrained people.

Ease of Use

The NaioSTM’s innovative design not only provides excellent performance but also makes it incredibly simple to operate. In terms of setup, the user only needs to connect two cables: power and USB. Due to the lack of high voltage and its overall strong construction, it is safe to be handled by students or other users with no prior training.

Scanning tips are simply cut from Pt/lr wire and do not require any dangerous agents to etch. The entire procedure, from setting up to viewing the first good pictures, takes only a few minutes. The user-friendly program includes instructions to assist users with the measuring procedure.

Nanosurf’s scanning tunneling microscope has risen to the top of the field after more than two decades and three generations of development. With around 1500 instruments in use across the world, it is widely considered as the obvious choice for performing scanning tunneling microscopy in all sorts of educational settings and fundamental research due to its smart construction.

Professors and teachers like carrying out practical demonstrations on the NaioSTM as it is simple to use, and students find it incredibly motivating to be able to effectively complete hands-on experiments without extensive preparation.

Scanning tunneling microscopy is regarded as one of nanotechnology’s cornerstones. Nanosurf, when used in conjunction with the NaioAFM, brings atomic-scale nanotechnology to the classroom, bringing insights into biology, chemistry and physics.

Why is this STM so Popular in the Classroom?

  • Teachers are satisfied with how simple Nanosurf STMs operate, since it allows them to give their students rapid and easy demonstrations in the classroom.
  • Students are inspired by the quick results they get while utilizing the STMs during hands-on instruction.
  • Because the conducting tips are simply cut from Pt/Ir wire and do not need etching in toxic solvents, anybody may safely use a Nanosurf STM.
