A Review of Formation of Oxygen-Related Donors (ODs) and Impurity Concentration in Step-Annealed Czochralski Silicon
Abstract: Czochralski (CZ) silicon being one of the two methods of silicon crystallization, the one that is used commercially for device fabrication, needs to be studied more closely. Hence, the Generation and behaviour of thermal donors (TD) and new donors (ND) as a result of pre-annealing at moderate temperature 480°C of carbon-rich boron-doped (p-type) CZ-silicon has been studied here, as function of annealing time by Hall studies and resistivity measurements in …

Recent Advances in Crystal Defect Engineering of Semiconductor Photocatalysts for Sustainable Environmental and Energy Applications
Abstract: Semiconductor photocatalysis has emerged as one of the most promising green technologies for addressing environmental pollution and global energy challenges through solar energy utilization. Nevertheless, the practical application of conventional semiconductor photocatalysts is often limited by their narrow visible-light absorption, rapid recombination of photogenerated electron–hole pairs, insufficient active sites, and poor charge-transfer efficiency. Defect engineering has recently attracted significant attention as an effective strategy to overcome these limitations by deliberately …
