TL;DR: In this paper, the influence of the melt structure, from which an associated state is assumed, on the crystalline quality, the composition instability in conventional ampoules, the segregation behaviour of the excess component (normally tellurium), the axial distribution of inclusions and precipitations, the mass transport with an additional cadmium source, and the correlation between the vacancy and impurity segregation and the substrate purity as a function of axial crystal position.

TL;DR: An overview on the defect knowledge in IV-VI (PbTe), II-VI and CdTe and III-V (GaAs, InP) semiconductor compound crystals in dependence on non-stoichiometric growth conditions from the melt is given in this paper.

TL;DR: In this article, the main pros and cons of various types of magnetic fields in crystal growth are discussed and the advantages of travelling magnetic fields are presented. And the target of the current KRIST MAG project is devoted to the development of an internal heater-magnet module for coupled generation of temperature and a travelling magnetic field, suitable for incorporation into industrial Czochralski pullers and vertical gradient freeze equipments.

TL;DR: In this article, the density and distribution of inclusions of the excess component in CdTe and (Cd,Zn)Te crystals grown by the Bridgman method and by the travelling heater method (THM) have been investigated by transmission infrared (IR) microscopy.

TL;DR: In this article, a historical review of the development of knowledge of defect formation in semiconductor crystals is given, starting with zero-dimensional defect types, especially native point defects in Si and GaAs.
