Novel photocathodes using vacuum microelectronics technology
A new photocathode called a ‘‘photosensitive field emitter’’ has been proposed, and a prototype was fabricated. This new Ž . photocathode was realized using a gated Si field emitter tip and an hydrogenated amorphous Si a-Si:H p–i–n photodiode. The emission current from the photocathode is proportional to the illumination intensity, and detectable maximum of the illumination intensity was about ...
متن کاملArray Concepts for Solid-state and Vacuum Microelectronics Millimeter-Wave Generation
There is an increasing demand for compact watt-level COherent sources in the millimeterand submillimeter-wave region. The approach that we have taken to satisfy this need is to fabricate twodimensional grids loaded with oscillators and multipliers for quasi-optical coherent spatial combining of the outputs of large numbers of lowpower devices. This was first demonstrated through the successful ...
متن کاملSurface Conditioning Effect on Vacuum Microelectronics Components Fabricated by Deep Reactive Ion Etching
Advances in material processing such as silicon micromachining are opening the way to vacuum microelectronics. Two-dimensional vacuum components can be fabricated using the microsystems processes. We developed such devices using a single metal layer and silicon micromachining by DRIE. The latter technological step has significant impact on the characteristics of the vacuum components. This pape...
متن کاملDislocations in Microelectronics
This brief review monitors the use of small crystalline defects, such as dislocations, in the design of diodes, bipolar and field effect transistors along the microminiaturization trend in electronics. Attempts to make dislocation based electronic components were driven at various stages by the development of semiconductor technology and were inspired by successes of miniaturization. In the ear...
متن کاملThe Materiality of Microelectronics
This study advocates for ‘materials-centered’ accounts in the history of technology, and presents such an analysis for the early history of microelectronics. Innovations in semiconductor crystal production were central to the emergence of solid state electronics and the dynamics of the early semiconductor industry. In the late 1940s and early 1950s, the Bell Telephone Laboratories developed nov...
