ABACUS Tool Suite and Bipolar Junction Transistors - Fall 2023

Explore the ABACUS tool suite and Bipolar Junction Transistors in this 37-minute video lecture from the Semiconductor Education Recitation Series. Gain insights from Dr. Gerhard Klimeck of Purdue University as he provides an overview of ABACUS and demonstrates the Bipolar-Junction-Transistor-Lab. Learn how to experiment with npn and pnp BJTs in both ideal 1D and realistic 2D geometries. Discover how to manipulate doping profiles, layer thicknesses, and material systems including Si, Ge, and GaAs. Understand how the lab computes internal device quantities such as charge profiles, band edge profiles, and recombination rates at equilibrium and applied bias. Examine terminal currents through Gummel plots and common emitter output current, while exploring transistor beta as a function of collector current. Investigate the effects of different minority carrier lifetimes on transistor performance. Gain hands-on experience with PADRE, an industrial tool used by Bell Labs for transistor design.
