    Description / Table of Contents: ESR Studies of Radiation Processes in Phosphate GlassesRadiation processes in phosphate glasses are investigated by ESR and optical measurements. ESR shows a hole-centre in the systems K2O/P2O5 and K2O/MGO/P2O5 which depends on manner and concentration of the cations. Its nature is explained in somewhat a different way than given by BEEKENKAMP or by MIURA and HASEGAWA. Another hole-centre which is independent of cations is discussed in agreement with optical investigations. The electrons set free by radiation react with O2 solved in the glass or with cations. The particels Ag0, Ag2+, Ag+2 have been found and Agn+4 may be present too in the system K2O/MgO/Ag2O/P2O5. The system K2O/MgO/Tl2O/P2O5 shows analogous reactions, but full explanation of the lines could not yet be given.
    Notes: Durch ESR-Untersuchungen und Vergleiche mit optischen Messungen werden Aussagen über die durch Bestrahlung in Phosphatgläsern ablaufenden Vorgänge gemacht. In den Systemen K2O/P2O5 und K2O/MgO/P2O5 wird durch ESR-Messungen ein kationenabhängiges Lochzentrum gefunden, dessen Natur in Abweichung von den Modellen nach BEEKENKAMP und nach MIURA u. HASEGAWA erklärt wird. Ein weiteres kationenunabhängiges Lochzentrum wird in Übereinstimmung mit optischen Untersuchungen gedeutet. Die durch Bestrahlung freigesetzten Elektronen lagern sich an im Glas gelösten Sauerstoff (O2) an oder reagieren mit den Kationen. Im System K2O/MgO/Ag2O/P2O5 werden die Teilchen Ag0, Ag2+, Ag+2 gefunden und Agn+4 wahrscheinlich gemacht. Für das System K2O/MgO/Tl2O/P2O5 gelten analoge Verhältnisse. Eine ausführliche Zuordnung konnte aber dabei noch nicht vorgenommen werden.

    Description: In an effort to evaluate the minority carrier lifetimes in CVD-epitaxially grown layers in their dependence on the CVD process variables, the absolute spectral LBIC method was found to be the only available method capable of yielding both lifetime and surface recombination velocity in layers, independent of the resistivity of this layer or that of the substrate, as long as they are separated by a pn-junction. With this method, it was not only possible to determine the minority carrier lifetimes in as-grown epi-layers, but to observe their changes through the device fabrication processes. In addition, it was possible for the first time to determine the lifetimes in the alloy-regrowth p(+) layers of base high/low junction structures.

    Description: A generic comparison has been carried out of all methods for recombination parameter determination that are based on measurement of a current and/or voltage in either steady-state, transient, or frequency-dependent approaches. The theoretical background for the time-dependent methods has been extended from prior work to include drift fields and be applicable to compound (multilayered) regions. The key findings were: (1) all methods have essentially the same limitations to determination of only the dominant recombination parameters; (2) open-circuit measurements have more sensitivity to the recombination parameters than short circuit measurements, but they present much more difficulty in eliminating spurious effects; (3) transient and frequency-dependent methods have exactly the same expressions for the relaxation constants and the breakpoint frequencies; and (4) in compound regions there exists only one set of relaxation constants for all the coupled layers. These constants include all relevant parameters of these layers. It is thus difficult to separate these parameters in time- or frequency-domain measurements. ASLBIC seems still to be the most suitable method for determination of emitter parameters.
