    Mathematical Modeling of Czochralski Type Growth Processes for Semiconductor Bulk Single Crystals

    This paper deals with the mathematical modeling and simulation of crystal growth processes by the so-called Czochralski method and related methods, which are important industrial processes to grow large bulk sing...

    Kinetic solutions of the Boltzmann-Peierls equation and its moment systems

    The evolution of heat in crystalline solids is described at low temperatures by the Boltzmann-Peierls equation, which is a kinetic equation for the phase density of phonons.

    Modelling and Simulation of Capacitor Impulse Welding

    We present a numerical simulation of capacitor resistance welding. The model accounts for electrical, thermal and mechanical effects, which are nonlinearly coupled by the balance laws, constitutive equations a...

    Heat pulse experiments revisited

    This is a review of heat propagation — theory and experiment — in dielectric solids at low temperatures where the phenomenon of second sound occurs. The review does not merely present a list of the various exp...

    Kinetic Theory of Phonons in Glasses

    Glasses below 1 K show a qualitative similarity of their thermal properties which can be explained by the widely accepted tunneling model. The most controversially discussed consequence of the tunneling model ...

    Entropy and causality as criteria for the existence of shock waves in low temperature heat conduction

    A set of symmetric hyberbolic field equations, describing heat conduction in dielectric solids at low temperatures, is studied with respect to the propagation of temperature shock waves. The field equations ha...

    Regelungseigenschaften Monomineralischer Gesteine bei Gerichteter Beanspruchung

    In a hydrostatic stressfield mineral grains do not show any preferred orientation. In uniaxial stress we will expect preferred orientation for the crystallites. With optical and electrical methods the preferre...
