1. On the role of the electron-electron interaction in two-dimensional quantum dots and rings
Sammanfattning : Many-Body Perturbation Theory is put to test as a method for reliable calculations of the electron-electron interaction in two-dimensional quantum dots. We show that second order correlation gives qualitative agreement with experiments on a level which was not found within the Hartree-Fock description. LÄS MER
2. Quantum dot biomarkers for tracking endothelial progenitor cells and activated endothelium
Sammanfattning : The development of new visualization techniques is essential in the field of bioimaging to gain deeper knowledge about various medical and biological events at the cellular and molecular levels. Quantum dots (QDs) are semiconductor nanocrystals which are opening new perspectives in biotechnology due to their powerful optical properties and high stability. LÄS MER
3. Theoretical Studies of Electron Transport in Quantum Dot Structures
Sammanfattning : We calculate the phase property of the reflection coefficient in two-terminal structures using a lattice tight-binding model. It is seen that, provided that there exist two coherent reflection paths, the reflection probability can be zero for certain electron energies. LÄS MER
4. Molecular Electronics - Modeling, Devices and Architecture
Sammanfattning : Molecular electronics is an area of micro/nanoelectronics with a number of farreaching goals and challenges: denser implementation of electronic memory and logic, less expensive manufacturing, smaller or more sensitive measurement devices, selfassembly of devices and systems and, last but not least, exploring new science and applications.In recent years, molecular electronics has expanded into a broader field of molecular-scale electronics, partly because molecular components have to be defined in solid-state contexts via lithography and self-assembly, and effectively become hybrid devices with new and interesting properties.
