Three Semiconductor Device Models Using the Density-Gradient Theory
You can use the density-gradient theory to model semiconductor devices. Here are 3 examples: a Si inversion layer, Si nanowire MOSFET, and InSb p-channel FET.
Intro to Density-Gradient Theory for Semiconductor Device Simulation
The density-gradient theory is a computationally efficient way to include quantum confinement in the conventional drift-diffusion formulation commonly used for simulating semiconductor devices.
How the B-H Curve Affects a Magnetic Analysis (and How to Improve It)
Magnetic soft iron steels are widely used as core materials in motors, transformers, and inductors. The B-H curve is used to describe the magnetization properties of such materials.
Simulating Radiation Effects in Semiconductor Devices
Analyzing radiation effects in semiconductor devices is an important capability for consumer electronics, medical imaging, nuclear engineering, aerospace, and a wide range of other industries.
