Shockley-Read-Hall Windows

1. Overview​

Shockley-Read-Hall (SRH) windows allow the user to define a rectangular region where the default carrier lifetimes for SRH recombination can be adjusted. Within this window, the carrier lifetimes are scaled by a constant factor, providing precise control over the recombination dynamics in specific regions of the device.

2. Usage Instructions​

To define an SRH window:

  1. From the Menu, select Define -> Window -> Shockley-Read-Hall.

  1. Use your cursor and mouse buttons to define a rectangular doping window.

  1. Once the window's shape has been defined the SRH window's properties dialog box will appear. Use this dialog to set the window's properties.

3. Parameters​
