Protecting Aerospace Devices via an Ion-Material Interaction Benchmark
In outer space and other harsh radiation environments, high-energy ions and protons pierce materials and affect nearby electronic systems. Known as a single-event effect (SEE), the particle radiation can lead to soft or hard errors in devices. Since just one hard error puts a space mission at risk, aerospace engineers must make sure that all critical electronic devices can withstand an SEE. To gain a better understanding of this phenomenon, they can accurately analyze the ion-material interaction using simulation.

Self-Consistent Schrödinger-Poisson Results for a Nanowire Benchmark
This benchmark model of a GaAs nanowire validates the Schrödinger-Poisson Equation multiphysics interface, which is useful for modeling systems with quantum-confined charge carriers.
