What do you see?
This configuration determines the InP carrier concentration analyzing a reflectance spectrum recorded at 30° angle of incidence and s-polarized radiation (using a gold mirror reference). The SCOUT simulation is shown in blue, measured data are displayed in red.
What can you do?
SCOUT has been configured for routine analysis which makes the operation quite easy: Import measured data, start the analysis, export the results.
Let's do that step-by-step:
Press the Import button and select the file inp_600_60.std which contains a (simulated) demo spectrum. After the file selection SCOUT shows the spectral range of the found data:
Just confirm this by pressing OK and see the new ‚measured' spectrum in red:
Now press Start and wait. After a while there will be some fitting activity and the Start button has turned into a red Stop button now). Wait until the fit stops automatically indicated by the restored Start button. The blue curve should now be close to the red one indicating a good agreement of simulation and measurement:
Now press the Export button to store the results of the fit in a table. If you face a dialog like
please answer Yes to proceed.
That's it. The carrier concentration is 6×10^18 1/cm^3. Applying a SCOUT solution can be that easy!
Before we will inspect the table with the results we will analyze some more spectra, i.e. do the sequence Import, Start, Export.
To practize, please do that for the files inp_1000_25.std, inp_2000_40.std, inp_300_20.std, and finally inp_50_20.std.
Now press the Workbook button. This opens an Excel compatible workbook with information about the fit results. Line 7 gives the investigated files, lines 9 and 10 the fit parameter values. In addition to the carrier concentration the damping constant of the Drude model that is used here has also been varied during the fit.
You can save the workbook in several formats (including Excel 5) or select a range and Copy it to the clipboard.
