    Surface elastic-wave propagation, transduction, and amplification (in a piezoelectric semiconductor) are discussed with emphasis on characteristics useful in electronic devices. Computed curves show the dependence on distance from the surface of the elastic and the electric fields associated with surface elastic-wave propagation in cadmium sulfide. The interaction impedance, relating the external ... View full abstract»

    The problem of determining the necessary impurity distribution function which will minimize the minority carrier emitter-to-collector transit time is considered. The use of this optimum profile affords a possibility of improvement in the overall high-frequency performance of diodes and transistors. A simple one-dimensional geometry is assumed, and the drift and diffusion components of minority cur... View full abstract»

    The solution of Poisson's equation and the equation of motion by numerical methods is discussed. By considering the truncation error due to the use of difference equations in the one-dimensional case, it is shown, on the basis of a perturbation theory, that the error in the solution is proportional to the mesh sizeh. This theory is shown to be in good agreement with numerical solutions ... View full abstract»

  • The effect of drift length, beam radius, and perveance on klystron power conversion efficiency

    Current bunching calculations based on the disk electron model are used to determine the effect of drift length, beam radius, and beam perveance on the power conversion efficiency of a two-cavity klystron. In a 2.5 × 10-6perveance klystron, a loss in power output exceeding one decibel results when a drift length shorter than 0.08λqis used. Power conversion efficienc... View full abstract»

    A new method of measurement of the shot-noise reduction factor at microwave frequencies is described. In this method, the reduction factor is measured by using a traveling-wave phototube with oxide-coated cathode, on which an amplitude-modulated laser light is projected. The photodetected outputs, with and without the space-charge cloud near the cathode, are compared. The shot-noise reduction fact... View full abstract»

    A general formula is derived for gain of a distributed amplifier using nonuniform lines but with image impedance match at each connection. A study of the gain formula shows that the rise of gain can be eliminated by having different propagation functions for the sections. Thus a new method of constructing amplifiers having constant gain is obtained. The new amplifier also shows pronounced improvem... View full abstract»
