You will have a chance to work on a state-of-the-art 4-probe scanning tunneling microscope combined with ultrafast optical excitation.
The experimental work ranges from manipulation of matter with light to atomic-scale manipulation with precisely enginnered tips with superconducting or magnetic properties.
