High-resolution AFM/STM/IETS imaging and its applications

Dr. Pavel Jelinek

Institute of Physics of the Czech Academy of Science

High-resolution AFM/STM/IETS imaging of molecules acquired functionalized tips [1] created a lot of excitement among researchers from many fields including material science, physics and chemistry [2]. Here we will briefly describe a common underlying mechanism responsible for the unprecedented sub molecular contrast [3] including an efficient simulation approach of AFM/STM/IETS images. In next, we will also discuss applications of the technique achieving a precise identification of molecular products of on-surface reactions [4], imaging electrostatic field of molecules with sub molecular resolution [5] or discrimination of molecular spin states.
