Measurements of the Hall constant and mobility in the temperature range 81–1100 °K were carried out on n-type CdO single crystals with defect concentrations of 1.9–31.7 × 1018/cm3. Carrier concentrations were found to be independent of temperature, indicating complete ionization of the defect donors and semimetallic conduction. At high temperature the mobility appears to be limited by optical phonon scattering, while at low temperature ionized defect scattering is the dominant process. The apparent increase of the effective mass at low temperatures from 0.15 m0 to 0.45 m0 with increasing defect concentrations is ascribed to increasing nonparabolicity of the conduction band resulting from the addition of donor states to the band.

A new dynamical theory has been developed based on Yoshioka's coupled equations for describing inelastic electron scattering in thin crystals. Compared to existing theories, the primary advantage of this theory is that the incoherent summation of the diffracted intensities contributed by electrons after exciting vast numbers of different excited states has been evaluated before any numerical calculation. An additional advantage is that the phase correlations of atomic vibrations are considered, so that full lattice dynamics can be combined in the phonon scattering calculation. The new theory has been proven to be equivalent to the inelastic multislice theory, and has been applied to calculate energy-filtered diffraction patterns and images formed by phonon, single electron and valence scattered electrons.A calculated diffraction pattern of elastic and phonon scattered electrons for a parallel incident beam case is in agreement with the one observed (Fig. 1), showing thermal diffuse scattering (TDS) streaks and Kikuchi pattern.
