How to fix image disorders in SEM
Today, the scanning electron microscope (hereinafter abbreviated to SEM) is utilized not only in medical science and biology, but also in diverse fields such as materials development, metallic materials, ceramics, and semiconductors. This instrument is getting easier to use with the progress of electronics and introduction of new techniques. Anybody can now take micrographs after short-time training in its operational procedure. However, when one has begun to use the instrument, he cannot always take satisfactory photos. When the photo is not sharp enough, or when necessary information cannot be obtained, it is necessary to think what causes it. This paper is based on a set of common problems that arise when working with scanning electron microscope and fixing these problems will be discussed as well as how to achieve the maximum desired results from the sample. It is hoped that this article will be of help to those who are currently using Scanning Electron Microscope or will be used in the future.
