What is it about?
This manuscript provides an original solution to the problem of electron energy loss spectroscopy (EELS) resolution limitation. We strive to concentrate on the underlying physical effects and how they might be used to solve this complex practical challenge. The so-called low-macroscopic field emission (LMFE) discussed in this article is a noteworthy phenomenon that is currently lacking in terms of its applications since there is still no consensus in the academic community regarding its physical nature. We present a complex investigation on that matter including synthesis, formal analysis and physical modelling of an EELS system comprising such a novel LMFE emitter.

Why is it important?
The obtained results indicate the possibility to achieve a significant growth in energy and temporal resolutions, as well as a decrease in the detection threshold of chemical elements with trace concentrations while maintaining relatively high emission current density values.
