Abstract

The present invention provides forms of cesium compounds, more specifically cesium oxides, with higher stability and ease of handling, suitable to be used in electronic devices, e.g. photocathodes and NEA devices. The invention also provides a novel environmental chamber for use with an electron microscope.
