Webb4 maj 2007 · 6.4.1 Langmuir-Blodgett (LB) Films It has long been known that organic materials can spread upon a water surface to form thin films. Classical LB film techniques involve the dissolution of materials in suitable water immiscible solvents and spreading the resultant solution onto a water surface [53, 54]. WebbOn the other hand, the Langmuir–Blodgett (LB) film deposition technique is one of the best among few methods used to manipulate materials at the molecular level. In this article, the LB film preparation technique is discussed briefly with an emphasis on its application towards molecular electronics. Keywords: Langmuir–Blodgett films
