Langmuir-Blodgett Films-Certain organic materials are composed of amphiphilic molecules. When dispersed on a water surface, these types of materials can form an extremely thin film, just a single molecule thick. There are many practical applications for such ultrathin films, including insulating layers within semiconductor memory elements and biological membranes. I’m particularly looking forward to monitoring surface features of such films prior to deposition using a Brewster angle microscope.
Ferroelectric polymers- Ferroelectric materials are especially attractive for memory device applications, since they can become permanent sources of a switchable electric field. The two directions of the ferroelectric’s internal electric field can be used as the ‘1’ and ‘0’ of binary code. Unlike other ferroelectrics, polymer ferroelectric films are suitable for flexible substrates. Furthermore, improved efficiency has been observed in organic solar cells which feature a ferroelectric layer fabricated using the Langmuir-Blodgett technique.
