    This first part of a four part paper describes fifteen solid-state phenomena and physical effects. These phenomena are part of a group whose effects depend upon either the transport of electrons and holes or upon the band structure of the material. View full abstract»

    Certain metals adhere to ceramics when sintered. This adherence is important in incorporating ceramic components in electronic devices. But understanding of the adherence mechanism is limited. A study of adherence is described in this paper, and an explanation of the adherence of metal coatings to glassy high-alumina ceramics is presented. View full abstract»

    The effect of substrate surface roughness on the thermal stability of nichrome thin film resistors is presented. This investigation was confined primarily to glass- and alumina-type substrates. Electron microscope surface morphology examinations made of alumina substrates, obtained from different sources, revealed some differences in microstructure. No particular microdefect or combination of defects could be rigorously related to the thermal aging data for alumina. Comparative results between glass and alumina, where differences in roughness were quite pronounced, gave corresponding large differences in stability during thermal aging. Oxidation based on surface roughness is suggested as the mechanism to account for the increase in resistance obtained on the nichrome films supported on alumina during thermal aging.

  • Fuel Cells

    A comparison is drawn between the theoretical efficiencies of heat-engines and fuel-cells in the conversion of chemical to electrical energy. The electrochemical principles governing the operation of fuel-cells are discussed. Short descriptions, including performance curves, are given of a few selected fuel-cell types including low, intermediate, and high temperature cells, and redox and regenerative cells. An example is given of a rough calculation of battery and fuel weight and volume for a given power level and total energy demand. View full abstract»
