Universal Behavior of Strain in Self-assembled Quantum Dots
05 May 2016 | | Contributor(s):: Hesameddin Ilatikhameneh, Tarek Ahmed Ameen, Gerhard Klimeck, Rajib Rahman
This resource contains the universal behavior strain files produced by Nemo5. Attached also a Matlab script that can utilize the these compact descriptive files to produce the full strain distribution. Supported QD shapes; Cuboid, Dome, Cone, and Pyramid. Supported material systems;...
TE/TM polarisation response of InAs/GaAs quantum dot bilayers
22 Oct 2015 | | Contributor(s):: Muhammad Usman
Quantum dot bilayers are strong candidates for the design of telecom devices working at 1300 nm wavelength range. Here we analyse - both experimentally and theoretically - their optical and polarisation properties.
Why quantum dot simulation domain must contain multi-million atoms?
11 Jan 2013 | | Contributor(s):: Muhammad Usman
The InGaAs quantum dots obtained from the self-assembly growth process are heavily strained. The long-range strain and piezoelectric fields significantly modifies the electronic structure of the quantum dots. This imposes a critical constraint on the minimum size of the simulation domain to...
Quantum Dot Quantum Computation Simulator
04 Aug 2012 | | Contributor(s):: Brian Sutton
Performs simulations of quantum dot quantum computation using a model Hamiltonian with an on-site magnetic field and modulated inter-dot exchange interaction.

On the Two to Three Dimensional Growth Transition in Strained Silicon Germanium Thin Films
31 Jan 2012 | | Contributor(s):: Brian Demczyk
Utilizing a model adapted from classical nucleation theory , we calculate a "critical thickness" for island formation, taking into account the surfaceenergies of the deposit and the substrate and the elastic modulus of the deposit, to which experimental results for CVD grown silicon germanium...

Quantum dot - Design a laser
07 Nov 2010 | | Contributor(s):: SungGeun Kim
This document is a real-life problem for the quantum dot lab tool. Basic knowledge on the operation principle of a quantum dot laser is needed to solve this test. The test requires the tested person to be familar with the quantum dot lab tool.
