ABACUS Tool Suite and Bipolar Junction Transistors (Fall 2023)

2023.09.07 Gerhard Klimeck, Purdue University This video is part of the Recitation Series for Semiconductor Education and can be found at: https://nanohub.org/groups/abacus/sem... The ABACUS tool can be found at: https://nanohub.org/tools/abacus In the fifth session, Dr. Klimeck will give a brief overview of ABACUS and demonstrate the Bipolar-Junction-Transistor-Lab. Students can experiment with npn and pnp BJTs in ideal textbook 1D geometries as well as realistic 2D geometries. Different experiments with variations in doping profiles, layer thicknesses, and material systems (Si, Ge, GaAs) can be explored. Bipolar-Junction-Transistor-Lab computes internal device quantities such as charge profiles, band edge profiles, and recombination rates at equilibrium and applied bias throughout the length of the device. It also computes the terminal currents in the form of a Gummel plot as well as common emitter output current. The transistor beta is explicitly computed as a function of collector current. Students can also explore intricate consequences of different minority carrier lifetimes. Bipolar-Junction-Transistor-Lab is powered by the industrial tool PADRE which was used at Bell Labs to design transistors.
