#### Description

ABACUS is a collection of tools for the teaching fundamental concepts of semiconductor devices. These concepts typically include lattices, crystal structure, bandstructure, band models, carrier distributions, drift, diffusion, pn junctions, solar cells, light-emitting diodes (LED), bipolar junction transistors (BJT), metal-oxide semiconductor capacitors (MOScap), and multi-acronym-device field effect transistors (madFETs).

ABACUS is the key element in the Tool-Powered Curriculum on Semiconductor Device Education.
