Modeling the quantum dot growth in the continuum approximation
12 Jan 2011 | Publications | Contributor(s): Peter Cendula
Quantum dots can grow spontaneously during molecular beam epitaxy of
two materials with different lattice parameters, Stranski-Krastanow growth mode.
We study a mathematical model based on the continuum approximation of the
growing layer in two dimensions. Nonlinear evolution equation is solved …

In quantum mechanics the time-independent Schrodinger's equation can be solved for eigenfunctions (also called eigenstates or wave-functions) and corresponding eigenenergies (or energy levels) for a stationary physical system. The wavefunction itself can take on negative and positive values and …

Bandstructure of Carbon Nanotubes and Nanoribbons
14 Jun 2007 | Learning Modules | Contributor(s): James K Fodor, Seokmin Hong, Jing Guo
This learning module introduces users to the Carbon-Nano Bands simulation tool, which simulates the bandstructure of Carbon Nanotubes (CNTs) and Nanoribbons (CNRs). To gives users a strong background in bandstructure, the module starts with sections that introduce bandstructure basics. To this …
