   Sammanfattning : This licentiate thesis reports analytical results for the electrostatic response to a test charge moving through dusty plasma. Two particular cases for a slowly moving test charge, namely, grain size distribution and grain charging dynamics are considered. LÄS MER

4. 3. Shuttle Transport of Charge in Normal and Superconducting Nanostructures

   Författare :Andreas Isacsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Josephson effect; superconductivity; nanoelectromechanics NEMS ; single electron tunneling; coulomb blockade;

   Sammanfattning : In nanoscale systems, accumulation of charge is associated with large charging energies. If the forces arising due to the Coulomb interaction are comparable to the rigidity of the structures mechanical deformations can couple to the electronic degrees of freedom. LÄS MER
