Abstract : Self-assembled multilayer fabrication technology offers the ability to implement and replicate a wide variety of cost-competitive submicron-scale and low-power microelectronic, optoelectronic, and physical transducer devices for uses in military and consumer communication, instrumentation and display systems. Ionic self-assembled monolayer (ISAM) techniques for the fabrication of multilayer nanoparticle/polymer structures offer low manufacturing costs, advantages of processing at ambient temperature and pressure, ability to produce devices on a variety of substrate materials, and broad multifunctional tailing of materials response through the selective incorporation and long-range ordering of specific organic and inorganic molecules. F&S has modified the ISAM process to incorporate judiciously selected inorganic nanoparticles and organic polymers to form multilayer thin-films having enhanced electronic, optical, magnetic and other functionalities. Due to ultrasmall nanoparticle size and tight size distribution control, multiple quantum size effects have been demonstrated in such systems for the first time, suggesting the ability to control electronic material properties. F&S has also shown that ISAM processing inherently results in the spontaneous regular geometric ordering of noncentrosymmetric thin-film structures that display ferroelectric-like behavior, and nonlinear optical (NLO), electrooptic, piezoelectric and other responses, also for the first time.
