The purpose of this project is to use Kelvin probe and ambient photoemission measurements to measure energy levels of organic and hybrid semiconductors, and relate the results to the performance of these materials in photodiodes and sensing applications. The project aims to identify ways in which the above techniques can give new insight into organic and hybrid semiconductor materials and devices. In particular it aims to develop a measurement technique to determine the LUMO of an organic semiconductor which is important both for explosive sensing and for selection of appropriate acceptors for photodiodes. In addition scanning measurements will lead to imaging of the electronic properties of materials. It will progress the state of the art by providing new information and optoelectronic techniques to enable rational design of materials and devices. The resulting new knowledge is expected to be in the domains of materials science, device physics and instrumentation.

该项目的目的是使用开尔文探测器和环境光电子能测量来测量有机和混合半导体的能级，并将结果与这些材料在光电二极管和传感应用中的性能联系起来。该项目旨在确定上述技术可以为有机和混合半导体材料和器件提供新的见解的方法。特别是，它的目标是开发一种测量技术来确定有机半导体的LUMO，这对于爆炸物传感和选择适当的光电二极管接受者都是重要的。此外，扫描测量将导致对材料的电子性质进行成像。它将通过提供新的信息和光电子技术来实现材料和器件的合理设计，从而进步最先进的技术水平。由此产生的新知识预计将出现在材料科学、设备物理和仪器仪表领域。
