The paper is a review of technique and recent progress made in organic thin films grown in ultrahigh vacuum by organic molecular beam epitaxy techniques. The purification of source materials and the effects of impurities on organic thin films were also introduced. Both the natures of thin film growth and structural ordering from a theoretical and an experimental viewpoint have been discussed. Ultrahigh vacuum organic molecular beam epitaxy has been shown to be a highly versatile technique for the growth of a wide range of organic and hybrid organic/inorganic thin film structures which comprise a promising new class of engineering materials for optical and electronic device applications.
