­New Transistor Design Saves on Power

A nanoscale rendering of the two materials, graphene (gray) and chromium oxide (blue). The red and green arrows represent spin.

The new design was developed by University of Nebraska–Lincoln’s Christian Binek and University at Buffalo’s Jonathan Bird and Keke He. Along with energy saving, the new design could cut the number of transistors needed to store certain types of data by up to 75%, leading to smaller devices. It is also n

Figure 1. Typical B-H curve from positive saturation to negative saturation. When H is zero there exists Br which requires -Hc to return to zero. The area within the loop is core loss per cycle

What are AC Losses and why are they important? This paper discusses the physical effects and which issues must be observed by design engineers. Furthermore, an approach to determine AC losses with unmatched accuracy is being introduced. In 1892 Charles P. Steinmetz, working for General Electric presented his no
