Transparent conducting oxides (TCOs) are technologically important as transparent electrodes in opto-electronic devices as light emitting diodes and solar cells, but also for other applications as sensors. Previous studies at TU Darmstadt have identified fundamental differences in surface properties of In2O3 and ZnO, which are assumed to be related to a different bulk defect chemistry of the materials. In order to clearly identify such a correlation, which will impact the development of new TCO materials, the project aims at a systematic comparison between bulk and surface properties of TCOs. It will also provide a database on electronic surface properties of most recently developed TCOs. The goals will be achieved in a joint effort between Northwestern University (Evanston, USA) and Technische Universität Darmstadt (Germany), which combine expertise in TCO bulk synthesis, defect and transport analysis (NU) with expertise in TCO thin film deposition and surface and interface analysis (TUD). The proposal sets forth the recently initiated international collaboration between the groups as part of the ¿Materials World Network¿.

透明导电氧化物（TCO）在技术上是重要的，其作为光电器件（如发光二极管和太阳能电池）中的透明电极，但也用于传感器等其它应用。先前在达姆施塔特工业大学的研究已经确定了In2O3和ZnO的表面性质的根本差异，这被认为与材料的不同体缺陷化学有关。为了清楚地识别这种相关性（这将影响新的TCO材料的开发），该项目的目标是系统地比较TCO的体相和表面性质。它还将提供一个关于最近开发的TCO的电子表面特性的数据库。这些目标将在西北大学（美国埃文斯顿）和达姆施塔特工业大学（德国）的共同努力下实现，这两所大学将联合收割机在TCO块体合成、缺陷和输运分析（NU）方面的专业知识与TCO薄膜沉积和表面与界面分析（TUD）方面的专业知识结合起来。该提案阐述了最近发起的作为“材料世界网络”一部分的各小组之间的国际合作。
