Creating a Wavelength Tunable LED Simulation App
Thanks to the Semiconductor Module and the Application Builder, developing custom optoelectronic simulation apps has never been easier. In this blog post, we show you how to turn a model of an LED device into a user-friendly application that can be used to assess the impact of different designs on the LED’s emission characteristics and performance. We also demonstrate the use of custom methods to manipulate the solution data, enabling the easy creation of bespoke analysis tools.
How to Perform a 3D Analysis of a Semiconductor Device
Simulation of 3D semiconductors has the potential to be extremely useful when developing and improving semiconductor technology by reducing the amount of experimentation and fabrication required to design complex devices. Modeling 3D devices is challenging as the length scales that must be resolved, combined with the nonlinear nature of semiconductor physics phenomena, often require computationally expensive simulations. Here, we share an example simulation of a 3D bipolar transistor and important advice for effective modeling of 3D semiconductors with COMSOL Multiphysics.
Investigating LED Efficiency via Multiphysics Simulation
Bright light-emitting diodes (LEDs) are revolutionizing the lighting industry and blue LEDs in particular are ushering in a new age of widespread efficient LED lighting. The importance of blue LEDs was marked by this year’s Nobel Prize in physics, which went to the inventors. But, because bright LEDs are driven by larger currents, they suffer from reduced efficiency — a phenomenon known as LED droop. Using multiphysics simulations, we can investigate and understand the mechanisms behind LED efficiency.
