Few areas of investigation have benefited more from the use of the electron microscope than thin films. This is most strikingly demonstrated by the state of knowledge of the structure and growth mechanisms prior to and subsequent to electron microscope investigations.The use of the electron microscope as an experimental chamber in which both growth and observation take place simultaneously, has been responsible primarily for the broad quasi-quantitative view of the process of formation of thin films we now hold. The great advantage of the in situ experimental arrangement lies in its ability to examine in detail the time sequence of events occuring during thin film nucleation and growth. Each stage in the process of formation of thin films has been examined, and although questions still remain as to the exact mechanisms involved, the general features are well characterized. These are nucleation of ad-atom clusters on the substrate, growth of the atom clusters both laterally and perpendicular to the substrate, coalescence of the nuclei into larger sub-units and finally, elimination of channels between the extended islands.
