Frequency Dependence of Material Properties
One or more PRAP analysed resonance files can be
added to a PRAP compound file (of extension '.PZC'). By including
resonance spectra analysed using different order resonance peaks, or
by including the resonance spectra for samples having the same
dimension aspect ratio and different resonance lengths, the frequency
dependence of material properties can be studied. The added resonance
spectra should in general be acquired at the same DC bias voltage,
temperature, etc.
To study the effect of time on the material properties;
Open a new compound file with the 'New Compound
File' command of the File menu. Using the 'Add PZF File' command of the File
menu, add the spectra you wish to study. Ensure that each spectrum has been analysed.
You can do this by displaying each included resonance scan with the
'Display Resonance Scan' menu command from the Window menu. Selected the 'Display Axes' command of the
Window menu. For the x-axis, select Frequency. For the y-axis, select the material property
to be studied. The list of available properties is limited to those
available from the analysed resonance spectra included in the
compound file. Select 'OK'. The real and imaginary parts of
the selected property will be plotted as a function of frequency. The results can be copied to another Windows
application with the Copy command of the File menu. |
