In-situ gas monitoring by laser induced fluorescence spectroscopy
Monitoring of silicon suboxide activity is an important parameter in experiments relevant for silicon metal production. In previous work a reactor with optical access to the reaction zone, by use of a sequence of sapphire, UV fused silica and IR transparent sapphire and CaF2 windows, was designed. I...
Microstructure of multicrystalline silicon seeded by polysilicon chips and fluidized bed reactor granules
Multicrystalline silicon displays a considerable smaller average grain size and reduced dislocation generation when being seeded by polycrystalline silicon chips or fluidized bed reactor silicon granules. A simple texture analysis shows how the initially random grain structure of the seeds develops ...

Structure and dislocation development in mono-like silicon
The current paper investigates the structure of low-lifetime areas observed in a <110>-oriented mono-like silicon ingot grown from monocrystalline seeds. These areas are related to dislocation clusters forming at seed junctions and several generation mechanisms are discussed. Dislocations gene...
