We detected and solved an issue saving fit parameters in configurations which contain several interband transitions. When you load such a configuration some fit parameters may point to the wrong susceptibility. If you recompute the optical model the result is a kind of garbage, in most cases.
If you are experiencing this problem you should load the configuration and delete all fit parameters before you update the optical model. It is then safe to generate new fit parameters and save the configuration using program versions generated after June 2, 2015.
The computation of depth dependent, local absorption in layer stacks is much faster now.
This improvement speeds up objects of type “Local absorption” in the list of distributions, but also objects of type “Layer absorption” and “Charge carrier generation” in the list of spectra.
In CODE the computation of the integral quantity “Photo current” benefits from the enhancement.
Objects of type ‘parameter variation’ in the list of special computations keep the highest and lowest y-values and the corresponding x-values. You can retrieve these values as optical functions and show them in a view.
Here is an example:
The SCOUT technical manual has been updated – it contains a documentation of parameter variation objects as members of the list of special computations. Here is a link:
Pressing the key h in the main view immediately jumps to a default home configuration. You can set this configuration using the command File/Options/Set default home configuration. The setting will be stored for each user individually.
We have added some new commands in the submenu ‘Actions’ which turned out to be practical when fitting many oscillators of organic materials in the infrared.
Set active material: Type in the name of a material (must be present in the list of materials) in order to select it for the actions below.
Select all parameters: Select all parameters of the active material as fit parameters.
Select oscillators: Selects all oscillator parameters of the active material as fit parameters. This is useful while adjusting models for organic materials in the infrared which may may have many oscillators. Manual parameter selection is tedious in such a case. Please note that for Kim oscillators (which are very much recommended) the parameter ‘Gauss-Lorentz switch’ is not selected since we found that in almost all cases absorption bands have a Gaussian line shape which is the default setting of Kim oscillators.
Select oscillator strengths: Selects all oscillator strengths of the active material as fit parameters.
The menu command File/Report produced a funny output in the workbook, but not the wanted list of susceptibility parameters. We have changed this feature back to the serious version of the output.
Objects of type “Multiple spectra view” do their automatic scaling more clever now, taking into account all active spectra.
These view objects can now be selected by a single mouse click and then scaled using the controls in the status bar, like field view objects. Also the little buttons R (restore graphics), A (automatic scaling) and E (edit graphics parameters) work with these objects.
