  This work introduces a new software package `Sesame' for the numerical
computation of classical semiconductor equations. It supports 1 and
2-dimensional systems and provides tools to easily implement extended defects
such as grain boundaries or sample surfaces. Sesame has been designed to
facilitate fast exploration of the system parameter space and to visualize
local charge transport properties. Sesame is distributed as a Python package or
as a standalone GUI application, and is available at
https://pages.nist.gov/sesame/ .
