  • Analysis of Neutron Damage in HighTemperature Silicon Carbide JFETs

    Neutron-induced displacement damage effects in n-channel, depletion-mode junction-fleld-effect transistors (JFETs) fabricated on 6H-silicon carbide are reported as a function of temperature from room temperature (RT) to 300°C. The data are analyzed in terms of a refined model that folds in recently reported information on the two-level ionization energy structure of the nitrogen donors. A value of 5 ± 1 cm-3per n/cm2is obtained for the deep-level defect introduction rate induced by the neutron irradiation. Due to partial ionization of the donor atoms at RT, the carrier removal rate is a function of temperature, varying from 3.5 cm-1at RT to 4.75 cm-1at 300°C. The relative neutron effect on carrier mobility varies with temperature approximately as T-7/2, dropping by an order of magnitude at 300°C compared with the RT effect. The results offer further support for the use of SiC devices in applications which combine high-temperature and severe radiation environments, where the use of Si and GaAs technologies is limited.

  • Stochastic Wave Theories

    This chapter presents a summary of the historical development of the statistical wave theories and new ideas, and key questions that may be outstanding or may need further attention. It also discusses the reciprocity relations for the radiative transfer. Radiative transfer has been applied extensively to geophysical remote sensing and scattering. Basic formulations of radiative transfer are closely related to neutron transport and Boltzmann's transport equation. It has been used in biomedical tissue optics, imaging, and ultrasound imaging of tissues. The Sommerfeld problem deals with radio waves over a flat earth. However, if people consider imaging of objects near the ocean surface or terrain, it may be necessary to study the effects of roughness of the surface. This is a study of "stochastic Green's function" for rough surfaces. This problem has been studied using Dyson and Bethe‐Salpeter equations for coherent and incoherent fields using the smoothed diagram method similar to Watson‐Keller studies.

  • Phonon Transport in Si Nanostructures

    This chapter develops a Monte Carlo (MC) method for solving the phonon Boltzmann transport equation (BTE) to perform more accurate heat transfer simulations in nanoscale Si devices. In order to evaluate the thermal conductivity, one can adopted one particle MC method, which enables obtaining the statistical convergence efficiently. The chapter uses the MC simulator to analyze the quasi‐ballistic phonon transport effect on the heat conduction in Si. It considers that the MC method is a good tool for studying the mixture regime between the ballistic and diffusive nature for the phonon transport. The chapter shows the realistic dispersion relation of phonons in bulk Si calculated from the adiabatic bond charge model, whose accuracy was validated through comparison with experimental neutron scattering data. The thermal conductivity of Si nanowires (SiNWs) was also calculated using the MC simulator. In nanostructures, phonons are frequently scattered at boundaries, which significantly impedes heat conduction.

  • Nuclear Power

    Nuclear power plants utilize the energy released in a nuclear reaction as the source of thermal energy to heat steam which in turn drives a steam turbine that is connected to a generator to generate electricity. The most common fuel used as a source of this nuclear reaction is uranium. This chapter discusses the differences between alpha, beta, gamma, and neutron byproducts of nuclear reactions. A reactor is a vessel that contains the nuclear fuel, control rods, and other systems to support the nuclear reaction. The boiling water reactor BWR design utilizes light water for both coolant and moderator. The boiling water reactor (BWR) only has one loop and the reactor is the "boiler" in the thermodynamic cycle. The pressurized heavy water reactor (PHWR) uses heavy water as the moderator. Heavy water is a molecule that contains deuterium and oxygen as compared with light water which is a molecule that contains hydrogen and oxygen.
