Xps Peak Fit Software Free Download

once all processing is complete, the software can either export the results to a specified folder or as a single text file that can be imported into other software (e.g., r or python). the text file can be read by the xpsviewer software itself, as well as by other software tools.

a tutorial for non-experts is available. the tutorial has examples for users with a basic understanding of the xps equipment and the xps analysis process. each tutorial gives step-by-step instructions, including screen shots, on how to use the software.

this software can be used to peak fit xps spectrum obtained from the surface analysis of various materials.xpspeak is a free software package that is available to all users. you can use it to fit the xps data. xpspeak can extract various parameters such as area, full width at half maxima, peak shift and peak area. the original xps peak software is available for windows, linux and mac. for the windows version, you can download the software from the website as well as the installation file. there is a single file or executable file named xpspeak.exe which contains a self-contained matlab function that you can use to fit the xps data. the software is written in a single m-file and you do not need to have the matlab toolbox installed. the matlab function can be called from the command line. the following command will do a peak fit of the xps spectrum of a given material:

the peakfit module in xpspeak can be used to fit various xps peaks:

peakfit(signal,center,window,numpeaks,peakshape,extra,numtrials,start,autozero,fixedparameters,plots,bipolar,minwidth,delta,clipheight)

this peakfit function takes as input a signal that contains xps peaks. the signal can be one or more files. it can also be a single peak. the input signal must contain peak, trough, and background data. the user can define the peak, trough, and background baselines for each xps peak manually or by using the peakfit gui. the user can define the width of each peak using either a fixed width or the user defined scale from the gui. the user can define the number of trials to use to fit the data. the peakfit function finds the best fit to the data. it can optionally use fixed peak or user defined values for the peak area, width, and shift. the peakfit function does not generate a list of best fit values for the parameters. the user can use the peakfit function to examine the baseline data and peaks after the fit using the following commands:

peakfit(signal,center,window,numpeaks,peakshape,extra,numtrials,start,autozero,fixedparameters,plots,bipolar,minwidth,delta,clipheight)

the peakfit function fits the data using a non-linear least squares algorithm. the peakfit function has options for forcing the user to use fixed peak areas or user defined values. the best fit parameters are output in a file (named outputfilename.mat) that can be loaded into matlab. the peakfit function works on 32-bit windows 7 and higher or 64-bit windows vista and higher. you can use the peakfit function to fit xps peaks on systems with different matlab versions.

one of the most difficult aspects of the analysis is the fitting. there are a lot of factors that can effect the signal and the fitting. how large the sample is, how flat is the sample, what is the sample-to-detector distance, what is the voltage of the beam, what is the temperature of the sample, what is the pressure, what is the quality of the surface, how far into the bulk is the signal, how thick is the sample, how thick is the surface film, and how are the binding energies assigned in the spectrum. these are just a few of the factors that can affect the signal and the fitting. these are all adjustable in the software and are handled automatically, but the parameters for the fitting are only as good as the starting values for the fitting.
essentially, the saxis program is designed to help you check the validity of a peak position as a function of wavelength. it is actually an auxiliary program. it is used to check the results of a peak fit routine for the positions and widths of peaks, or to check the positions of peaks within an experimental spectrum. it is also used to determine the amount of noise in an experimental spectrum.
xpspeak 4.0 is a powerful fit program for x-ray photoelectron spectroscopy (xps) and auger electron spectroscopy (aes) data. it can be used for standard curve fitting of element-specific peaks, data base searching and peak quantification. the program is easy to use and supports all major xps systems.
