A finite element analysis of a silicon based double quantum dot structure
S. Rahman, J. Gorman, C. H. W. Barnes +2
We present the results of a finite-element solution of the Laplace equation for the silicon-based trench-isolated double quantum-dot and the capacitively-coupled single-electron tr…

A numerical investigation of a piezoelectric surface acoustic wave interaction with a one-dimensional channel
S. Rahman, M. Kataoka, C. H. W. Barnes +1
We investigate the propagation of a piezoelectric surface acoustic wave (SAW) across a GaAs/AlGaAs heterostructure surface, on which there is fixed a metallic split-gat…

A finite element method for modelling electromechanical wave propagation in anisotropic piezoelectric media
S. Rahman, H. P. Langtangen, C. H. W. Barnes
We describe and evaluate a numerical solution strategy for simulating surface acoustic waves through semiconductor devices with complex geometries. This multi-physics problem is of…
