A Multi-Functional Organic Charge Coupled Device

在硅上制造的电荷注入器件（CID）和电荷耦合器件（CCD）具有广泛的应用，最常见的是在图像捕获中，例如在数字相机和天文学中的敏感图像阵列中。这些器件由彼此相邻制造的双层电容器阵列组成。一层是半导体，另一层是绝缘体。在这些器件中，电荷在半导体/界面处以电学或光学方式感应。通过在连续的电容器上施加合适的电压，这些电荷可以通过阵列从一个电容器移动到下一个电容器。CID仅由两个电容器组成，但对于研究电荷从一个电容器到另一个电容器的生成和传输效率非常有用。CCD是一个多电容器阵列。在我们最近发表的有机CID之前，没有实验室以前报告过这两种设备的有机版本。本项目旨在演示一种多功能有机电荷耦合器件（CCD）。最初，该计划将展示我们对有机CID的开创性演示，该CID本质上是一个单级CCD。我们计划利用CID的光学响应来研究器件的界面物理。我们将研究专门选择的绝缘体/半导体组合，以获得在绝缘体/半导体界面的电荷传输和捕获的动力学的基本信息。这些信息将使我们能够设计和制造最佳的测试结构，并确定适当的测试条件，以证明一个多功能的有机CCD。该设备为信号处理和成像应用提供了机会，这些应用与印刷塑料电子系统兼容，这是英国政府的一个关键投资领域。

The charge injection device (CID) and the charge coupled device (CCD) fabricated on silicon have a wide range of applications, the most common being in image capture for example in digital cameras and sensitive image arrays in astronomy. These devices are composed of arrays of two-layer capacitors fabricated adjacent to each other. One layer is a semiconductor, the other an insulator. In these devices charges are induced at the semiconductor/interface either electrically or optically. By applying suitable voltages across successive capacitors these charges can be moved through the array from one capacitor to the next. The CID is composed simply of two capacitors but is extremely useful for studying the generation and transfer efficiency of charges from one capacitor to the other. The CCD is a multicapacitor array. Until our recent publication of an organic CID no laboratories had previously reported organic versions of these two devices. This project is directed at demonstrating a multi-functional organic charge coupled device (CCD). Initially the programme will characterise fully our groundbreaking demonstration of an organic CID which is, in essence, a single-stage CCD. We plan to utilise the optical response of the CID to investigate the interface physics of the device. We will study specifically chosen insulator/semiconductor combinations in order to obtain the essential information on the dynamics of charge transport and trapping at the insulator/semiconductor interface. This information will allow us to design and fabricate the optimum test structure and identify the appropriate test conditions for demonstrating a multi-functional organic CCD. The device offers opportunities for exploitation in signal processing and imaging applications that are compatible with printed plastic electronic systems, a key investment area for the UK Government.
