Data is continuously uploaded, and upon the completion of SM3, an open-access database containing all the data will be made available
The packaged MATLAB application is a data processing tool to enable colouring of hyperspectral image volume datasets from secondary electron hyperspectral imaging (SEHI).
The methodology of the colour enriched SEHI (CSEHI) approach is described in section 3.2 and 3.3 of the article:
“Insights into surface chemistry down to nanoscale: An accessible colour hyperspectral imaging approach for scanning electron microscopy”.
Figure 1 of the article is a pictorial flow diagram representation of the workflow that is followed by the CSEHI application.
Data for 'Low-voltage SEM of air-sensitive powders: From sample preparation to micro/nano analysis with secondary electron hyperspectral imaging'
SEHI data volumes included in 10.1016/j.micron.2022.103234.
For methodology of preparation, collection and data processing see section 5 of the published article.
Corresponding SEHI data volume metadata in .json format.
Automatic iFAST Spectral Acquisition (Step 0.6V Range-15-20.4 V)
This is an automatic iFast collection recipe (iFast developers kit version 3.0.16.1738) which steps the Mirror Voltage between -15V and 20.4 V (Energy range of -1.6 to 11.6 eV.) An image (frame time 0.5 seconds) is collected with each successive 0.6 V with no pauses between images. This batch of images can then be analysed to create S Curves and SE Spectra.
