UMD Microfluidic Device Manipulates and Positions Quantum Dots

Finding ways to see, position, measure, and accurately manipulate nanoscale objects is an ongoing challenge for researchers developing the next generation of ultra-compact electronics, sensors and optical devices. Even the most advanced conventional microscopes are limited by diffraction of the shortest wavelength of visible light, about 400 nanometers, rendering them unable to produce images or measurements of objects that are significantly smaller than this threshold.

JQI Scientists Use Quantum Dots, Microfluidics and Plasmonics to Study Optical Nanostructures

Modern telecommunications happens because of fast electrons and fast photons. Can it get better? Can Moore's law---the doubling of computing power ever 18 months or so---be sustained? Can the compactness (nm-scale components) of electronics be combined with the speed of photonics? Well, one such hybrid approach is being explored at the Joint Quantum Institute (*), where scientists bring together three marvelous physics research fields: microfluidics, quantum dots, and plasmonics to probe and study optical nanostructures with spatial accuracy as fine as 12 nm.

MIT Team Overcomes Factors Limiting Quantum Dot Applications

Quantum dots — tiny particles that emit light in a dazzling array of glowing colors — have the potential for many applications, but have faced a series of hurdles to improved performance. But an MIT team says that it has succeeded in overcoming all these obstacles at once, while earlier efforts have only been able to tackle them one or a few at a time.
