Optoelectronics – solid state optical devices
Published in David Jiles, Introduction to the Electronic Properties of Materials, 2017
Field emission displays (FEDs) operate using cathode luminescence which is the same principle that is used in the cathode ray tubes. However, in FEDs each pixel has its own pointed electrode which emits the electrons, which then accelerate across to the anode that is equipped with a phosphor so that light is emitted once the electrons strike it. Essentially, therefore, the FED is an assembly of very small cathode ray tubes, as shown in Fig. 12.12.
Graphene Applications in Optoelectronic Devices
Published in Kuan Yew Cheong, Two-Dimensional Nanostructures for Energy-Related Applications, 2017
A Field Emission Device (FED) is a device that functions based on electron extraction from the material surface by quantum mechanical tunneling (Fowler and Nordheim 1928). This simple principle has been widely used in field emission displays and electron guns (Brodie and Schwoebel 1994, De Jonge and Bonard 2004). Figure 4.14 shows a basic diagram of an FED with a graphene emitter.

Nowadays, Field Emission Displays (FED) have been widely used in television, computers as well as in laboratories and medical applications. Figure 1 shows the three parts of the FED screen (http://escience.anu.edu.au/lecture/cg/Display/FED.en.html). Microtips, so-called electron guns, are on the cathode, which emit electrons. In order to manufacture these microstructures, lithography etching technology and micro-machining technology have been applied. However, these methods are usually complex and high cost. Recently, hot embossing technique has been proposed to fabricate microstructures on glass substrate. Compared to the above methods, hot embossing is more simple, productivity and the quality of final products is better. Especially, micro-formability of glass material could be improved with the assistance of ultrasonic vibration.
