Abstract
The emission characteristics of a cathode consisting of an array of p-type Si pyramidal field emitters have been studied. Using advanced computerized technique for a comprehensive analysis of the properties of field emission structures, the process of activation of emission sites, operation of the cathode in the mode of relative stability of the current level, as well as field emission in the mode of extreme and unstable currents were analyzed. The field emission orthodoxy test demonstrated the difficulty of describing the performance of Si tips using the classical Murphy-Good theoretical formalism for metals. Using Morgulis-Stratton theory, which takes into account the features of field-electron emission from the semiconductor, a simulation of the properties of the cathode under consideration was carried out, and analysis of its experimental current-voltage characteristics was performed. The calculated field enhancement factor at the top of the Si pyramidal field emitter coincided with the value obtained from the experiment with high accuracy.
期刊介绍:
Sensors and Actuators A: Physical brings together multidisciplinary interests in one journal entirely devoted to disseminating information on all aspects of research and development of solid-state devices for transducing physical signals. Sensors and Actuators A: Physical regularly publishes original papers, letters to the Editors and from time to time invited review articles within the following device areas:
• Fundamentals and Physics, such as: classification of effects, physical effects, measurement theory, modelling of sensors, measurement standards, measurement errors, units and constants, time and frequency measurement. Modeling papers should bring new modeling techniques to the field and be supported by experimental results.
• Materials and their Processing, such as: piezoelectric materials, polymers, metal oxides, III-V and II-VI semiconductors, thick and thin films, optical glass fibres, amorphous, polycrystalline and monocrystalline silicon.
• Optoelectronic sensors, such as: photovoltaic diodes, photoconductors, photodiodes, phototransistors, positron-sensitive photodetectors, optoisolators, photodiode arrays, charge-coupled devices, light-emitting diodes, injection lasers and liquid-crystal displays.
• Mechanical sensors, such as: metallic, thin-film and semiconductor strain gauges, diffused silicon pressure sensors, silicon accelerometers, solid-state displacement transducers, piezo junction devices, piezoelectric field-effect transducers (PiFETs), tunnel-diode strain sensors, surface acoustic wave devices, silicon micromechanical switches, solid-state flow meters and electronic flow controllers.
