Thin Glass Layers as Supports for Electron Microscopy

Abstract

IN the usual technique of electron microscopy, ‘Formvar’ or collodion layers are used as supports. We have been studying the electrical properties of thin metallic layers and determined their structure by means of the electron microscope. The electrical resistances were made on glass strips, while ‘Formvar’ layers were used as support for the electron microscope examination. We have always hesitated to consider the picture obtained on ‘Formvar’ as identical with the structure obtained on the glass surface; therefore we tried to use very thin glass layers as supports, and eventually succeeded.
