  • Ionization Processes

    The ionization process of atoms or molecules is through energizing the electrons causing them to leave stable orbit revolving around the nucleus and becoming free-moving charges. The main mechanisms for ionization consist of thermal, electron impact, chemical reactions, photoionization, and microwave or electron cyclotron resonance. This chapter describes the ionization that focus on the basic mechanisms of photoemission, thermal, and electron impact discharges. The equilibrium ionization of the mixture of electrons, ions, and neutral particles can be analyzed by the law of mass action and the electronic partition function. Under gas discharge conditions, ionization by electron impact dominates over the photoionization because the cross sections of photoionization close to the ionizing threshold are rather high. The chapter provides Saha equation of ionization. An important parameter for the ionization rate is the mean free path of the gas medium and is ultimately related to the collision cross section.

  • Overview

    This chapter introduces recent challenging studies of SOI-Lubistor-based devices and new pn-junction-based devices, and addresses their future prospect. Attention is given to operations of the _i_-MOS transistor, tunnel FET, feedback FET, offset-gate Lubistor, and SOI fin LED.

  • Electrical Breakdown in Gases

    This chapter discusses a short treatise on atomic collisions in gases and a description of Townsend's experiments in the early twentieth century. It presents the Paschen curve, and describes the predominant theories of spark formation. The chapter also discusses other breakdown phenomena, such as coronas and the hollow electrode carrier generation used in pseudosparks. Electrical breakdown occurs in a gas when a high¿¿¿conductivity channel is formed between cathode and anode. Before a study is made of the behavior of gases under the influence of an electric field, it is appropriate to review the basic principles of the kinetic theory of gases pertinent to gaseous ionization and breakdown. From there, the various concepts of ionic and electronic can be inferred. The chapter further discusses the efficient use of gaseous insulation with intershields. It concludes by discussing the important aspects of breakdown behavior in gaseous SF6.

  • Modeling Electron Impact Ionization

    Electron impact ionization is the mainstay for plasma-based flow control actuators because it actuates in less than microseconds and the electrode configuration can be made nonintrusive to oncoming stream. In addition, when the actuator is not needed, unlike most mechanical flow control devices, it will not be parasitic and degrade performance of aerospace vehicles. The space charges induce an additional electric field potential that makes it different from the corona discharge. This chapter presents the best physics-based, multifluid model for the electron impact ionization. The physics for electron impact ionization is well known through the luminary contributions by Townsend, the ionization is evolving from the electrons collision, secondary emission, and avalanche. The secondary emission from cathode arises as controlling mechanism for all electron impact ionization. A high concentration of positive charges over an electrode creates an extremely high electrical field potential, which is comparable to the magnitude in a nuclei.

  • Feasibility of the Lubistor-Based Avalanche Phototransistor

    In the twenty-first century, the traffic carried by optical communication systems will grow year by year, and the provision of rock-solid communication reliability is mandatory. Quantum communication technology is one of the most promising candidates for realizing truly reliable communication. Although the scientific and engineering bases for quantum communication remain under development, many scientists and engineers are carrying out challenging research to try to achieve significant breakthroughs in the near future. I have tried to discuss how the new Lubistor will contribute to meeting the technological challenges.

  • Optimization and Comparison of Power Devices

    We begin this chapter with a discussion of avalanche breakdown and blocking voltage in power devices, which leads naturally into a survey of edge termination techniques. We then discuss the optimum design of unipolar drift regions in devices such as Schottky diodes, JFETs (junction field-effect transistors), and MOSFETs (metal-oxide-semiconductor field effect transistors), with a brief discussion of lateral RESURF (reduced-surface- field) devices. Finally, we present a consistent methodology for optimizing and comparing unipolar and bipolar devices for a particular set of specifications (i.e., blocking voltage and switching frequency).

  • Fundamentals of Electrical Discharges

    Natural phenomena, such as gamma rays produced by radioactive decay processes in the soil and cosmic radiation originating from solar flares and other galactic objects, can ionize the air molecules. This chapter first discusses ionization and deionization processes in gases. This is followed by a discussion on ionization and attachment coefficients. Two typical breakdown mechanisms occur in gases, each of them operating under specifically favorable conditions: Townsend's mechanism and the streamer mechanism. Corona discharges in air can burn on the overstressed zones of hot electrodes. This kind of discharge occupies a short layer, attached to the energized conductor. When a conductor is in corona, then the electric field on the surface is somehow influenced by the surrounding ion space charge. Kaptzov's hypothesis (KH) relates to the assumption that the space charge emitted into the interelectrode gap is in amounts that hold the surface field at the onset level.
