Modeling a MOS Capacitor with the Semiconductor Module

June 20, 2018

MOS capacitors (MOSCAPs) contain 3 main parts: a semiconductor body or substrate, an insulator film, and a metal electrode (or gate). You can use the Semiconductor Module to model MOSCAP designs.

Learning Quantum Mechanics Concepts with Double-Barrier Structures

August 30, 2017

Quantum mechanics is a notoriously difficult subject to learn — and teach. Modeling a double-barrier structure is an effective way to teach quantum mechanics concepts to physics students.

Computing the Band Gap in Superlattices with the Schrödinger Equation

May 31, 2017

You can easily compute the effective band gap for a superlattice structure by using a predefined Schrödinger Equation interface and building a simulation application.

Analyzing a Silicon Solar Cell Design with the Semiconductor Module

April 27, 2017

You can model a solar (or photovoltaic) cell consisting of a 1D Si p-n junction using the Semiconductor Module add-on. We feature a tutorial model to provide more details.

Study Sensor Performance in Rapid Thermal Annealing with Simulation

December 16, 2016

In rapid thermal annealing, a process step in producing semiconductors, measuring the temperature of a wafer is key. Without accurate measurements, overheating and nonuniform temperature distributions may occur, both of which impact the effectiveness of the process. This is why tools like the COMSOL Multiphysics® software give you the ability to analyze temperature distributions within an RTA design. From these results, you can better assess the performance of the sensor component and optimize its configuration to achieve accurate measurements.

Simulation Paves the Way for More Efficient OLED Devices

April 7, 2016

When it comes to creating the next generation of flat panel displays and solid-state area lighting, organic light-emitting diodes, or OLEDs, may be used to help. While recognized for its various advantages, this emerging technology suffers from some weaknesses that reduce its overall efficiency. One such example is light loss, which is partially caused by the plasmon coupling effect. Looking to reduce the effect’s prominence in OLED devices, researchers from Konica Minolta Laboratory turned to the COMSOL Multiphysics® software.

Calculating the Emission Spectra from Common Light Sources

January 14, 2016

I love my Philips Hue lighting system, which I bought over a year ago. The system allows you to set millions of different colors and thousands of brightness levels for up to 18 bulbs using a smartphone. You can also program the system to automatically turn on as you approach your residence, known as geofencing, or at specific times of the day. But how does the light quality compare to that of other lighting technologies?

Creating a Wavelength Tunable LED Simulation App

May 18, 2015

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.
