Contacts{ }¶
- Calling sequence
Contacts{ ... }- Properties
usage: \(\mathrm{\textcolor{ForestGreen}{optional\;within\;the\;group}}\)
- Functionality
Defines contacts for simulation of devices with open boundary conditions.
- Example
Contacts{ DensityLeft = 1e18 DensityRight = 1e18 Broadening = 10.0 Ballistic = no }
Note
See the tutorial — DEV — AlGaAs/GaAs resonant tunneling diode for example usage.
