Journal ArticleDOI
Confinement of electrons to quantum corrals on a metal surface.
TL;DR: Tuning spectroscopy performed inside of the corrals revealed a series of discrete resonances, providing evidence for size quantization and STM images show that the corral's interior local density of states is dominated by the eigenstate density expected for an electron trapped in a round two-dimensional box.
Journal ArticleDOI
Imaging standing waves in a two-dimensional electron gas
TL;DR: In this paper, standing-wave patterns in the local density of states of the Cu(lll) surface using the scanning tunnelling microscope (STM) at low temperature were observed.
Journal ArticleDOI
Quantum mirages formed by coherent projection of electronic structure
TL;DR: The projection of the electronic structure surrounding a magnetic Co atom to a remote location on the surface of a Cu crystal is reported; electron partial waves scattered from the real Co atom are coherently refocused to form a spectral image or ‘quantum mirage’.
Journal ArticleDOI
An atomic switch realized with the scanning tunnelling microscope
TL;DR: In this paper, the operation of a bistable switch that derives its function from the motion of a single atom is reported. But the switch is a prototype of a new class of potentially very small electronic devices which we will call atom switches.
Journal ArticleDOI
Spin coupling in engineered atomic structures.
TL;DR: This work used a scanning tunneling microscope to probe the interactions between spins in individual atomic-scale magnetic structures and observed excitations of the coupled atomic spins that can change both the total spin and its orientation.
