Abstract
This paper will discuss a microscope that allows high energy resolution spectroscopy to be performed at high spatial resolution. This instrument uses a high magnetic field to contain and focus electrons emitted from the sample surface and has a twoβdimensional detector that records a photoelectron image. It is also equipped with a hemispherical analyzer, which allows stateβofβtheβart spectroscopic performance to be obtained from very small areas. The instrument is unique in that it collects a much larger solid angle than any other instrument in use today, and spatial resolutions of 2 ΞΌm and energy resolutions of 0.25 eV have been achieved.

An energy-filtering transmission electron microscope with 300 kV acceleration voltage was developed and the spatial resolution of elemental distribution images was improved. Observing oxygen monolayers in Al 11 O 3 N 9 , it was shown that the actual resolution attained is up to 0.5 nm. Surface plasm
Recently it has been shown that high resolution photoemission spectroscopy can be used to measure the energy gap of the high T c superconductors. The purpose of this paper is to review the results obtained by this technique and to compare the values of 2 &fKT c with those measured by tunneling or in
