Nanoelectronic Modeling Lecture 32: Strain Layer Design through Quantum Dot TCAD

04 Aug 2010 | Online Presentations | Contributor(s): Gerhard Klimeck, Muhammad Usman

This presentation demonstrates the utilization of NEMO3D to understand complex experimental data of embedded InAs quantum dots that are selectively overgrown with a strain reducing InGaAs layer. Different alloy concentrations of the strain layer tune the optical emission and absorption wavelength of the quantum dots. The role of the non-linear strain behavior ovserved in the experimental data is explored in NEMO3D. The simulation engine serves as a virtual microscope to understand the interplay of disorder, strain, and quantum dot shape.
