Reactions in Thin Metal Films Bombarded by the High Intensity Electron Microscope Beam
Published online by Cambridge University Press: 06 March 2019
Extract
The electron beam of the electron microscope is an excellent source of energy for producing localized observable reactions in thin films.
The normal operating beam of a double condenser lens System focussed for studying a metal film in good thermal contact with its mount gives a calculated temperature rise of about 20° to 50°C. However, by changing these specified conditions, the sample may be heated to temperatures well over 1000°C. Copper and gadolinium--melting points 1083°C and 1312°C respectively--have been melted in the electron microscope beam, as have BeO whiskers--melting point 2530° + 30° C--by the authors and their colleagues.
