Magnetic nanostructures have long been in the focus of intense research in the magnetic storage industry. For data storage the nonvolatility of magnetic states is of utmost relevance. As information technology generates the need for higher and higher data- ...
In recent years, the fabrication of novel ultrathin film systems featuring multi-functionalities has been extensively studied due to their potential applications in photonics, sensors and solar cells. In a general sense, the primary goal of the present the ...
For further miniaturization of magnetic data storage devices, instruments for exploring magnetic nanostructures are needed. Hall sensors provide a non invasive technique for quantitative magnetic field detection. In contrast to the highly sensitive semicon ...
Quantum dots (QDs) are nanoscopic semiconductor crystals. Electronic transitions inside QDs lead to photon emission with unique properties. Photons can for instance be emitted as triggered single photons or as pairs of correlated photons with different ene ...
A quantum dot is a semiconductor nanostructure that confines the motion of conduction band electrons and valence band holes in all three spatial directions, thus creating fully discrete energy levels. The confinement in the InAs/GaAs material system is gen ...
This thesis presents a novel approach for optical tri-dimensional contouring, requiring only one acquisition to extract a contour depth. It is based on an interferometric setup, using a reduced coherence light source, and is fully adaptable to endoscopic p ...
Challenges in nanotechnology today involve controlling dimensions, inter-particle spacing, surface coverage and behavior/response of functional nanostructures. Creating or placing nanostructures on surfaces is important for applications like data storage, ...
This paper proposes SC++lite, a sequentially consistent system that relaxes memory order speculatively to bridge the performance gap among memory consistency models. Prior proposals to speculatively relax memory order require large custom on-chip storage t ...
Current optical storage devices such as DVDs have their read/write capabilities fundamentally restricted by the diffraction limit of light. We present an optofluidic architecture for storing cocktails of colloidal quantum dots in electroactive nanowell str ...
CdSe quantum dots (QDs) with a high fluorescence quantum yield of 25% and a narrow size distribution were synthesized in a single step in H2O using glutathione as a stabilizing mol. The exceptional optical properties enabled for the 1st time the detection ...
