"Nanometer Positioning of Quantum Dots with Microfluidics"

by Chad Ropp

Friday, April 16, 2010 -- 12:00 p.m.
Large Conference Room, 1207 Energy Research Facility

Advisor:  Assistant Professor Edo Waks

Quantum dots are semiconductor nanocrystals that are stable single photon emitters which have the potential to be integrated with optical systems to form novel devices. One of the major difficulties in working with nanoparticles is the necessity of positioning the correct particles at the correct location, often requiring nanometer accuracy. In this talk I will describe a manipulation technique based on electroosmotic flow control in a microfluidic device that we used to position single quantum dots with nanometer precision. Using this technique we demonstrate in situ measurements on actively controlled nanoparticles and deterministic immobilization at the surface of our device.
