Quiz — Ansys Lumerical CHARGE — Simulation Objects

Which of the following can result in a more refined mesh in the simulation?

The mesh may not be adequately refined if the “max refine steps” in Auto Refinement Settings is not large enough to reach the limits defined by the mesh constraints.

Select the material types for which a doping object is applicable

You are performing an iso-thermal steady-state CHARGE simulation. Which of the following boundary conditions are available for your simulation

You need to simulate the photo-current of a single wavelength infrared photo-detector. Which of the following source objects best suit your application?

You have a 2D charge monitor in your simulation. What would be the unit of charge carrier densities returned by the monitor?

You cannot edit your geometry objects when you are in Partitioned volume mode.

Assume that your 2D simulation region is formed of only 2 domains: an inner domain and an outer domain. You want a boundary condition to be assigned to all of the boundaries of the simulation region (or in other words, the outer boundary of the outer domain). Which of the following reference geometries can be used to accomplish this?

You have three structures in your simulation: circle1, circl2 and circle3. The material and mesh order for each geometry object are as follows:

To be able to form a single domain object from multiple geometric objects, they should be made of the same material.

The use of open simulation boundaries is necessary to create an arbitrarily shaped simulation region.

Reference geometries can be used to define the geometry of structures such as rectangles and spheres.

Imagine you have an aluminum contact in your device which you need to apply a surface recombination to. What should be the status of “apply to majority carriers” option in surface recombination boundary condition settings for this contact?

Imagine you have a semiconductor domain in your simulation where you applied two constant doping objects to. One n-type with a concentration of 2e18, and one p-type with a concentration of 5e18. What would be the net doping concentration and type for this domain?

You want to assign a mesh constraint object to the entire volume of a geometric object available in the objects tree in your CHARGE simulation. Which of the following reference geometries will allow you to do this?

The 2d simulation region of the CHARGE solver is restricted to a rectangular shape.

Which of the following monitors can return the total net charge in a simulation domain in the units of coulombs?
