The central aim of the research is to produce electronic circuits into glass windows for visual display, monitoring and control purposes: 'transparent electronics'. The circuits are made from a very thin semiconductor-like material (ZnO: zinc oxide) and thin metal contacts. The materials are so thin (10's nm) that most of the light passes straight through. Thus 'intelligence' can be built into the window. The material used also offers optical advantages in that is 'low emissivity'; its refractive index serves to enhance the capture of solar energy and reduces the heat loss from the building. The added-value of introducing electronics capability into the glass coatings can open up a new generation of glass windows in buildings, cars and aeroplanes; especially for 'heads-up' displays. The last application is currently available using films containing indium. This is a very expensive material so its replacement with ZnO will bring down the cost and so open up the availabilty of such products. ZnO also has low-toxicity. The devices we will use are called metal-semiconductor field effect transistor (MESFET). These devices are chosen because they are very simple and easy to fabricate. They also operate at lower voltages than the more commonly used metal-oxide field effect transistor (MOSFET), which is found in computers and phones etc. The use of MESFETs avoids the need to develop a gate oxide technology which is very challenging technologically. The downside is that the digital circuits need to more complicated and so take up more space. However, the footprint of the circuits is less critical that for Si based chips, as the electronics is on large area panels. The project is then concerned with the establishment of a MESFET fabrication process, device design for the intended circuitry and finally design and realisation of basic circuit blocks and gate arrays.

这项研究的主要目的是将电子电路制作成玻璃窗，用于视觉显示、监测和控制目的：“透明电子”。电路是由一个非常薄的电容器状材料（ZnO：氧化锌）和薄的金属接触。这些材料非常薄（10纳米），大部分光线都可以直接通过。因此，“智能”可以内置到窗口中。所使用的材料还具有“低发射率”的光学优势;其折射率有助于提高太阳能的捕获并减少建筑物的热损失。在玻璃涂层中引入电子功能的附加值可以在建筑物、汽车和飞机中开辟新一代玻璃窗;特别是用于“抬头”显示器。最后一种应用目前可使用含铟的薄膜。这是一种非常昂贵的材料，因此用ZnO替代它将降低成本，从而打开此类产品的可用性。ZnO也具有低毒性。我们将使用的器件称为金属半导体场效应晶体管（MESFET）。选择这些器件是因为它们非常简单且易于制造。它们的工作电压也比计算机和电话等中更常用的金属氧化物场效应晶体管（MOSFET）低。使用MOSFET避免了开发栅极氧化物技术的需要，而栅极氧化物技术在技术上非常具有挑战性。缺点是数字电路需要更复杂，因此占用更多空间。然而，电路的占地面积不像基于Si的芯片那么重要，因为电子器件在大面积面板上。然后，该项目涉及MESFET制造工艺的建立，预期电路的器件设计，以及基本电路模块和门阵列的设计和实现。
