Research ArticleOpen accessIn the abstractStudy of Cutoff Frequency of High Collector Current Density in SiGe Single-Heterojunction Bipolar TransistorG. M. Khanduri, B. S. PanwarThe cutoff frequency performance of an NPN Si/SiGe/SiGe Single-heterojunction bipolar transistor (SiGe SHBT) at high collector current densities has been analyzed using a 2-dimensional MEDICI device simulator. A conventional NPN Si/SiGe/Si Double-heterojunction bipolar transistor (SiGe DHBT) having uniform 14%Ge in the base region has been investigated for comparison. The analysis shows the formation of a retarding potential barrier for minority … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 6,891 accessesView PDFCite
Research ArticleOpen accessIn the abstractFrom a Vicious Circle of Anxiety to a Virtuous Circle of Learning: Experience of Teaching Statistics to a Heterogeneous ClienteleMohammad Alauddin, James E. ButlerA considerable body of literature suggests that significant psychological barrier and anxiety characterize the teaching and learning process in statistics. This study investigates the incidence of statistics anxiety, the extent to which it can be overcome and the factors that contribute to the process of overcoming it. Self-study and overall teaching quality, amongst others, significantly contributed to this outcome. This … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 7,109 accessesView PDFCite
