Comparison of PCPBT Lab and Periodic Potential Lab
10 Aug 2009 | Online Presentations | Contributor(s): Abhijeet Paul, Samarth Agarwal, Gerhard Klimeck, Junzhe Geng
This small presentation provides information about the comparison performed for quantum wells made of GaAs and InAs in two different tools. This has been done to benchmark the results from completely …
Computational Nanoscience, Lecture 4: Geometry Optimization and Seeing What You're Doing
13 Feb 2008 | Teaching Materials | Contributor(s): Jeffrey C Grossman, Elif Ertekin
In this lecture, we discuss various methods for finding the ground state structure of a given system by minimizing its energy. Derivative and non-derivative methods are discussed, as well as the …
Computational Nanoscience, Lecture 6: Pair Distribution Function and More on Potentials
In this lecture we remind ourselves what a pair distribution function is, how to compute it, and why it is so important in simulations. Then, we revisit potentials and go into more detail including …
Cosine Bands: an Exercise for PCPBT
21 Aug 2008 | Teaching Materials | Contributor(s): Gerhard Klimeck, Dragica Vasileska
This exercise demonstrates the formation of cosine bands as we increase the number of wells in the n-well structure.
