MOLECULAR DEVICES USING LANGMUIR-BLODGETT-FILMS

Use of Langmuir-Blodgett (LB) films for the fabrication of devices at the molecular level is investigated. Because these films show control of order and dimensions in one direction only, they are not directly suited for this purpose. However, their properties are so intriguing and in many cases so much superior to other thin-film techniques that it is worthwhile to use them in combination with other technologies. We explored the application of LB films in the fabrication of molecular devices and suggested ways to make the dream come true. Our progress toward this goal is described, along with our attempt to build a memory system that uses an LB film as a storage medium and promises a capacity in the terabit range.
