The period's dominant theme was atomic-scale control coupled with emergent quantum transport in nanoscale systems. Scanning tunneling microscope manipulations demonstrated the assembly of individual atoms, laying the groundwork for atomically precise nanofabrication; simultaneously, nanoscale metal clusters connected to leads exhibited single-electron phenomena that foreshadowed quantum dot electronics. Colloidal nanocrystals and self-assembled molecular architectures further highlighted quantum confinement and discrete charging, with room-temperature Coulomb staircases and direct measurements of single nanocrystals validating nanoscale transport across diverse platforms.
