Fluorescent screen The high quality RHEED pattern is obtained with the RHEED screen of Vieetech Japan. Although a RHEED screen is the simple structure which coated the fluorescence material to glass, delicate cautions are required for the manufacture. If a fluorescence material is coated thickly, it becomes the cause of a charge up an electron beam and if uneven is in the thickness of a fluorescence material, uneven diffraction intensity will be caused. Therefore, production of a RHEED screen begins from sorting of a fluorescence material and is completed at last through many processes.
