在场致电子发射（FE）研究中，检查和分析实验电流-电压数据的质量和有效性是很重要的，这些数据通常以少数标准形式之一绘制。这些包括所谓的Fowler-Nordheim（FN），Millikan-Lauritsen（ML）和Murphy-Good（MG）图。场致发射正交性测试是一种简单的定量测试，旨在检查可以从这些图中提取的参数“缩放场”的值的合理性。这样做是为了确定从图中提取的表征参数是否可靠，或者可能是假的。本文总结了正统测试背后的理论，为每一个情节形式，并确认它是很容易应用到新开发的MG情节。一个简单的，新的，可访问的Web应用程序已经开发，提取缩放场值从任何这三个情节的形式，并测试缺乏场发射正统。
Abstract 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, alternatively, 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, new, accessible web application has been developed that extracts scaled-field values from any of these three plot forms, and tests for lack of field emission orthodoxy.
