Quantum dots are nano- or microscale devices created by confining free electrons in a 3D semiconducting matrix. Those tiny islands or droplets of confined “free electrons” (those with no potential energy) present many interesting electronic properties. They are of potential importance ... En savoir plus
This setup demonstrates how the characteristics of turbulent flow in a channel are modified by the presence of an adjacent porous region. Asymmetric velocity profiles, higher turbulence levels, and higher friction coefficients both at the solid wall and the fluid-porous interface are ... En savoir plus
As integrated circuit (IC) technology advances, with circuits becoming more powerful and compact, it is increasingly important to identify and prevent any cause of circuit failure. One particularly critical factor contributing to circuit failure is electromigration within the ... En savoir plus
This tutorial shows how to set up a multi-element objective lens. The chosen lens is the Double Gauss described in 'Modern Lens Design (2nd edition)', by W. Smith, 2005, pg 323. The tutorial demonstrates how to create a geometry sequence using the 'Spherical Lens 3D' part found in the ... En savoir plus
This model illustrates the refraction of light while passing through an optical prism using s– and p–polarized incident Gaussian beams. The prism boundaries are coated with anti–reflection coatings. It also calculates the reflectance and transmittance to analyze the performance of anti ... En savoir plus
It is often not possible to insert a normal microphone directly into the sound field being measured. The microphone may be too big to fit inside the measured system, such as for in-the-ear measurements for hearing aid fitting. The size of the microphone may also be too large compared to ...

A steel billet is quenched in oil from its austenitic state. A 2D axisymmetric model is used to simulate the coupled problem of austenite decomposition, heat transfer, and solid mechanics. During the quenching process, the austenite decomposes into a combination of ferrite, pearlite, ... En savoir plus
This model shows how to add several linked mobility models to the simple MOSFET example. En savoir plus
This model extracts spice parameters for a silicon p-n junction diode. The spice parameters are used to create a lumped-element equivalent circuit model of a half-wave rectifier that is compared to a full device level simulation. In this example, a device model is made by connecting a 2D ... En savoir plus
This model represents a test case of a flow in an elastic tube which is present in several applications. This specific case models viscoelastic flow and represents steady flow in a channel in which part of the upper wall is replaced by an elastic plate subjected to an external pressure. ...
