Growth, defect formation, and morphology control of germanium-silicon semiconductor nanowire heterostructures.

By the virtue of the nature of the vapor-liquid-solid (VLS) growth process in semiconductor nanowires (NWs) and their small size, the nucleation, propagation, and termination of stacking defects in NWs are dramatically different from that in thin films. We demonstrate germanium-silicon axial NW heterostructure growth by the VLS method with 100% composition modulation and use these structures as...

Fuzzy Logic Connectivity in Semiconductor Defect Clustering

In joining defects on semiconductor wafer maps into clusters, it is common for defects caused by different sources to overlap. Simple morphological image processing tends to either join too many unrelated defects together or not enough together. Expert semiconductor fabrication engineers have demonstrated that they can easily group clusters of defects from a common manufacturing problem source ...

Defect-Enhanced Electron Transport through Semiconductor Barriers

It has often been suggested that defects can enhance electron tunneling through barriers. Here, we derive a general expression of the current flowing through semiconductor barriers when induced by the presence of defects, taking into account tunneling and other possible mechanisms. Therefore, we calculate the capture probability of free electrons by defects located in the barrier and the subseq...

Neural Tube Defect and Folic Acid

نقص لوله عصبی یکی از ناهنجاریهای مادرزادی مهم و شایع می باشد که شیوع آن بیش از ۵/ ۴ در ۱۰۰۰ تولد زنده است. اتیولوژی و پاتوژنز بیماری هنوز ناشناخته است. مطالعات اخیر بر روی حیوانات نشان می دهد که این ناهنجاری ممکن است، ناشی از متابولیسم غیر طبیعی هموسیستئین باشد. در مطالعات اخیر مشخص شده است که پیشگیری از نقص لوله عصبی (NTD) بوسیله اسیدفولیک مؤثر می باشد.

Reduction in Defect Content of ODS Alloys

Oxide dispersion strengthened (ODS) alloys prepared by mechanical alloying (MA) and subsequent consolidation are of increasing interest for potential application in components for use in power generation and furnace applications. After MA, canned alloy powders are usually subjected to a series of heat treatments. These heat treatments, particularly those at higher temperatures, last long enough...
