For the last 35 years, the Scanning Tunnelling Microscope (STM) has transformed the way we perceive and understand materials at the atomic scale . The STM is the ideal technique for probing their electronic properties, and has been instrumental in the technological revolution particularly in assisting our understanding of new nano-materials that have been developed .
In this talk, I will discuss the STM studies we have performed in the Molecular Nanoscience Group. I will consider several experiments; from individual organic molecules adsorbed on semiconducting surfaces to self-assembled molecular layers on graphene. These studies probe the underlying physics and chemistry of the molecule-substrate and intermolecular interactions, the effects on the molecular states, and the role of the surface states on electron transport [3-5].
These studies reveal new electronic, optical, magnetic, and chemical properties can be explored at the level of a single atom or molecule. Our understanding of this molecular electronics is fundamental to the success of applications based on atomic-scale devices and memories, organic light emitting diodes, solar cells and sensors.
