Microscopy News
InAs Quantum Dots Self-Organize on Microdisks
Oct 1, 2005 — A self-organization process identified by scientists at Stanford University’s Solid State and Photonics Laboratory in California promises to facilitate the fabrication of devices in which quantum dots are coupled with microcavities, such as for proposed quantum information processing applications. They have found that InAs quantum dots formed on a prepatterned GaAs microdisk spatially align themselves in the cavity mode along the edge, which they attribute to preferential surface diffusion of...
