Identifying and Mitigating Anomalous Transparency in Retarding Potential Analyzers
Abstract
As an instrument for charged particle energy analysis, the often-employed gridded retarding potential analyzer is straightforward to construct and operate, but substantial error can arise in analyzing its output if the device's behavior deviates from the ideal. Interpreting the device's output as a charged particle energy distribution presumes that collected current is a monotonically decreasing function of the applied bias potential, but this is not the case in some configurations, in particular in applications where the device has been miniaturized; rather, in some regimes, an increasing current can be observed with increasing bias.
