MOS Capacitor Visualizer (1D)

This simulator is based on Matlab and Python simulators built by Dr. Sean Rommel at RIT. This code was converted to HTML/JS with accessibility under Dr. Rommel’s guidance and direction. If there are errors or mistakes they are my errors and mistakes. The “show calculations” are also my additions.
