A modular semiconductor characterization system to replace a legacy source measurement unit

我们的研究小组目前致力于聚合物光子器件，如聚合物发光器件和聚合物光伏电池。这项研究是在2003年在皇后大学建立的最先进的设施中进行的。我们的学生从头开始制造各种设计的聚合物器件，并进行电气，光学，扫描和低温表征，以阐明底层材料和器件物理。共轭聚合物是唯一已知的既具有塑料的机械和加工优势，又具有半导体的电学和光学特性的材料。在过去的二十年里，“塑料电子”领域取得了巨大的进展。聚合物发光二极管、太阳能电池和场效应晶体管都已被证明具有接近传统半导体器件的性能。柔性、大面积和低成本的固态照明板和太阳能电池板是我们研究的最终目标。我们的聚合物光子器件研究是独一无二的，因为我们器件的活性材料是聚合物混合离子/电子导体（MIECs），而不是原始聚合物。我们探索离子和电子电荷之间的相互作用，以提高我们的设备的性能。我们的实验装置研究不仅依赖于HQP的辛勤工作，还依赖于专业仪器。本提案的目标是获得急需的半导体表征系统，该系统将取代无法满足我们测试需求的传统源测量单元。

Our research group currently works on polymer photonic devices, such as polymer light-emitting devices and polymer photovoltaic cells. The research is carried out in a state-of-the-art facility established in 2003 at Queen's University. Our students fabricate polymer devices of various designs from scratch and perform electrical, optical, scanning, and low temperature characterizations to elucidate the underlying materials and device physics. Conjugated polymers are the only known materials that possess both the mechanical and processing advantages of plastics as well as the electrical and optical properties of semiconductors. The field of "plastics electronics" has enjoyed tremendous interest and progress in the past two decades. Polymer light-emitting diodes, solar cells and field-effect transistors have all been demonstrated with performance approaching that of conventional semiconductor devices. Flexible, large-area and low-cost solid-state lighting panels and solar panels are extremely attractive the ultimate goals of our research. Our polymer photonic device research is unique in that the active materials of our devices are polymer mixed ionic/electronic conductors (MIECs) instead of pristine polymers. We explore the interaction between ionic and electronic charges to improve the performance of our devices. Our experimental device research relies not only on the hard work of HQPs, but also on specialized instruments. It is the goal of this proposal to acquire a much-needed Semiconductor Characterization System that will replace an legacy Source Measurement Unit that can no longer satisfy our testing needs.
