Implementation of the orthodoxy test as a validity check on experimental field emission data
In field electron emission (FE) studies, it is important to check and analyse
the quality and validity of experimental current-voltage data, which is usually
plotted in one of a small number of standard forms. These include the so-called
Fowler-Nordheim (FN), Millikan-Lauritsen (ML) and Murphy-Good (MG) plots. The
Field Emission Orthodoxy Test is a simple quantitative test that aims to check
for the reasonableness of the values of the parameter "scaled field" that can
be extracted from these plots. This is done in order to establish whether
characterization parameters extracted from the plot will be reliable or,
alternative, likely to be spurious. This paper summarises the theory behind the
orthodoxy test, for each of the plot forms, and confirms that it is easy to
apply it to the newly developed MG plot. A simple web tool has been developed
that extracts scaled-field values from any of these three plot forms, and tests
for lack of field emission orthodoxy.Comment: 14 typescript pages, 2 figure
