STM: Scanning Tunneling Microscopy

Program: (19-22 February 2024)

The principles and applications of the scanning tunneling microscopy (STM) will be presented and then applied in a case study:  iron phthalocyanines deposited on metal surfaces before and after the oxygen dosage. The course can be divided in two parts: i)  a practical part in which the surfaces will be prepared and characterised on a UHV system and ii) a part in which DFT modelling will be used to interpret the experimental results.
