Abstract

The invention discloses a method for preparing a high vacuum field modulation organic micromolecule oriented nano-film and a system thereof. The nano-film is applicable to all organic semiconductor devices. The method comprises the steps: an evaporation boat (3) filled with organic micromolecule materials is electrified with direct current, and the evaporation rate of the organic micromolecule materials is controlled within the range of 0.1nm/s-0.3nm/s; a beam of white light with the light intensity of 100-1000 candela is emitted into a vacuum cavity in an incident way, a beam of linearly polarized light having the light vector direction being parallel to evaporation particle flow is obtained through a polaroid sheet (6) arranged in front of a glass window (7), and the orientation of the single organic micromolecule is modulated by the polarized light; the organic micromolecule nano-film which is distributed in an oriented way is formed. The system is provided with the glass window which is sealed with the cavity and has the diameter of 10cm in the middle of one side of a high vacuum evaporation cavity (1); the polaroid sheet having the adjustable direction is fixed closely to the glass window, and a white light source (5) with adjustable light intensity is placed in front of the polaroid sheet.

Description

technical field [0001] The invention relates to a field modulation method and system based on an organic small molecule oriented nano film, and the organic nano film can be applied to all organic semiconductor devices. Background technique [0002] In 2000, the American "Science" magazine listed the progress of organic electronics as one of the top ten scientific and technological achievements in 2000, including major discoveries such as the draft human genome and cloning technology. In the same year, the Nobel Prize in Chemistry was awarded to Hegel, McDiarmid, Hideki Shirakawa and others for their major breakthroughs in organic electronics and organic / polymer research. Therefore, people have reason to believe that with the deepening of organic electronics research and the improvement of the preparation process of organic electronic devices, a new era - the era of organic electronics will come. [0003] Organic electronic materials and their application in the field of inf...
