This simulation calculates the transmission and reflection coefficients for a single electron plane wave incident on a series of square barriers. It makes use of the transfer matrix method outlined in a series of lecture notes by Michael G. Moore from his PHYS 851 course in fall 2009. A PDF copy of Dr. Moore's lecture notes is provided in the directory labeled "papers".
The parameters for the simulation are listed in "lib/declare_parameters.m". All of the input parameters must be in SI units (joules, kilograms, and meters). In order to make conversions easier, "eV" and "nm" have been defined. Appending "*eV" to a value will convert eV to joules. Appending "*nm" to a value will convert nanometers to meters. For example:
- 10*eV => (10)(1.60217657e-19) joules
- 10*nm => (10)(1e-9) meters
Running "lib/simulation.m" returns two graphs - one with the transmission coefficient (T) as a function of incident energy and the other with the reflection coefficient (R) as a function of incident energy.
