Hello everybody. Today a special article: we spent most of our time writing the training report.

 

We became aware that we forgot to say something yesterday. Details. STM measures were made on the silicon sample (without lead islands).

The sample was not much cleaned (he had a long sample life and knew many outgassings and flashes) that's why it was hard to find the 7x7 reorganization of atoms thanks to the STM. A long part of the sample seemed not organized.

However, even if the organized surface was very small (near 3 nanometers), and even if the quality of the image is not very good, we succeeded to see the atoms!
