Nevertheless, surprisingly little is known about controlling interfacial reactions. This chapter briefly overviews what is known about interfacial reactions between bulk reactants and describes the use of superlattice reactants in the study and control of interfacial reactions. Unlike previous methods; superlattice reactants allow for the control of superlattice structure via layer-by-layer deposition, the ability to follow the thermodynamics of the initial stages of interfacial reactions by using calorimetry, and the ability to follow the evolution of interfacial structure by using the low-angle superlattice diffraction pattern. Several examples are presented that demonstrate these advantages. 关键词: POLY(METHYL-3-THIOPHENE); IN SITU AFM; STRUCTURE MODIFICATION; X-RAY-DIFFRACTION; SOLID-STATE REACTION; THIN-FILMS; DIFFUSION COUPLES; 1ST PHASE; MULTILAYER; KINETICS; SILICON; NUCLEATION; GROWTH 1ST PHASE; MULTILAYER; KINETICS; SILICON; NUCLEATION; GROWTH
