Effect of Local Deformation on the Emission Energy of  Quantum Dots in a Flexible Tube

S. Kiravittaya[1], P. Cendula[2], A. Rastelli[2], and O. Schmidt[2]
[1]Max-Planck-Institut für Festkörperforschung, Stuttgart, Germany
[2]Institute for Integrative Nanosciences, Dresden, Germany

Strain induced by local deformation of a flexible micrometer-sized semiconductor tube is quantified by modeling a ball pressing on the tube wall. By changing the pressing condition, we are able to change the strain state of the tube wall incorporating self-assembled quantum dots (QDs) in ... Per saperne di più

Finite Element Analysis of Ferrofluid Cooling of Heat Generating Devices

T. Strek
Institute of Applied Mechanics, Poznan University of Technology, Poznan, Poland

An external magnetic field imposed on a ferrofluid with a temperature gradient, results in a non-uniform magnetic body force, which leads to a form of heat transfer called thermomagnetic convection. A magnet placed near the device will always attract the colder ferrofluid more than ... Per saperne di più
