In the past five years, we have achieved a number of important studies on the interfacial chemistry of (a) bio/organic molecules on Si single-crystal surfaces, and (b) nanostructures of transition metals (and their oxides) and transparent conductive oxides on Si and other (templated) substrates. As material and structural imperfections have become an often unavoidable yet extremely important part of the entire material, we will focus, in the next five years, on defects-driven phenomena in these hybrid nanomaterials. While the presence of defects is often viewed as detrimental to some material properties, control of these defects can also be highly beneficial to a number of important material properties, especially when the material size approaches the nanoscale. This has been demonstrated by our recent discovery of extraordinary photocatalytic power in defect-rich TiO

在过去的五年中，我们已经取得了一些重要的研究（a）生物/有机分子在硅单晶表面上的界面化学，和（B）过渡金属（及其氧化物）和透明导电氧化物在硅和其他（模板）基板的纳米结构。 由于材料和结构缺陷已成为整个材料中通常不可避免但极其重要的部分，我们将在未来五年内专注于这些混合纳米材料中的缺陷驱动现象。 虽然缺陷的存在通常被视为对某些材料性能有害，但控制这些缺陷也可以对许多重要的材料性能非常有益，特别是当材料尺寸接近纳米级时。 我们最近在缺陷丰富的TiO中发现了非凡的光催化能力，
