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，我们已经在SI单晶体表面上（a）生物/有机分子的界面化学进行了许多重要研究，以及（b）过渡金属（及其氧化物）和SI和其他（模糊的）底物的过渡金属（及其氧化物）以及透明的导电氧化物的纳米结构。 随着材料和结构缺陷已成为整个材料中通常是不可避免但极为重要的部分，我们将在未来五年内集中在这些混合纳米材料中的缺陷驱动现象上。 尽管缺陷的存在通常被视为对某些材料特性有害，但对这些缺陷的控制也可能对许多重要的材料特性非常有益，尤其是当材料大小接近纳米级时。 我们最近发现了在缺陷丰富的TIO中的非凡光催化能力，这已经证明了这一点
