The metal-silicon-oxide (MOS) structure is the fundamental building block for many silicon planar devices. Its capacitance measurements provide a wealth of insight into the working principles of such devices. This tutorial constructs a simple 1D model of a MOS capacitor (MOSCAP). Both ... 詳細を見る
In a polymer electrolyte membrane electrolyzer cell (PEMEC), the two electrode compartments are separated by a polymer membrane. Liquid water is fed to the anode side, forming oxygen gas on the anode, and hydrogen gas on the cathode side, respectively. The respective designs of the ... 詳細を見る
Due to the large differences in length scales in a lithium-ion battery, with the thickness of the different layers typically being several orders of magnitude smaller than the extension in the sheet direction, a lithium-ion battery is often well represented by a one-dimensional model. ... 詳細を見る
The electron energy distribution function (EEDF) plays an important role in the overall behavior of discharges. In this example, the formation period of an Argon plasma is studied with special attention paid to the EEDF. The plasma is created within a 4 cm gap by a DC source voltage of 1 ... 詳細を見る
Schottky Contact This benchmark simulates the behavior of an ideal Schottky barrier diode made of a tungsten contact deposited on a silicon wafer. The resulting J-V (current density vs. applied voltage) curve obtained from the model under forward bias is compared with experimental ... 詳細を見る
This is a model of a MEMS microphone solved in the frequency domain including the DC prestress effects. The model is set up using the Electromechanics multiphysics interface, Thermoviscous Acoustics, and Pressure Acoustics. The microphone consists of a perforated plate and a prestressed ... 詳細を見る
A Mach-Zehnder modulator is used for controlling the amplitude of an optical wave. The input waveguide is split up into two waveguide interferometer arms. If a voltage is applied across one of the arms, a phase shift is induced for the wave passing through that arm. When the two arms are ... 詳細を見る
This tutorial uses a simple 1D model of a silicon solar cell to illustrate the basic steps to set up and perform a device physics simulation with the Semiconductor Module. A user-defined expression is used for the photo-generation rate and the result shows typical I–V and P–V curves of ... 詳細を見る
