Nanocrystalline materials: a way to solids with tunable electronic structures and properties?

摘要: It is the purpose of this paper to point out that nanometer-sized structures may open way modify electronic structure (e.g. charge carrier density) and related properties solids. The modification be achieved by means externally applied electric fields or internal fields. These affect density in a surface region which case nanostructured solids attain substantial fraction total volume. Tuning an field realized, for example, immersing chain (or network chains) interconnected, particles into electrolyte. Similarly, nanocomposites proposed deviate from one coarse-grained materials if large volume material consists electronically modified regions at interphase boundaries. Experimental observations supporting these ideas are discussed.
