Overcoming Design Challenges in High Performance …

Permanent magnet (PM) motors for EV appliions have unique design challenges. As electric motors become smaller and faster, designers must consider the potential effects of electrical drive frequencies, magnetic eddy currents, laminated steel core loss, mechanical stresses on the quickly rotating shaft (rotor dynamics), and electrical control of the motor through the inverter.

CVD diamond resolves thermal management issues in …

The CVD diamond heat spreader solution was found to have 30% lower thermal resistance at 0.300 mm in thickness at a thermal conductivity of 1000 W/mK (the original solution used a 1.00 mm thick BeO heat spreader). The lower thermal resistance of the diamond heat spreader has led to this device functioning with better RF linearity performance

GaN: The logical successor to silicon? - News

We believe that this record-breaking velocity stems from variable stress along the nano-channel, which produces significant variations in the conduction-band-edge. Such variations could create an electron launcher effect, leading to a quasi-ballistic transport across the channel, and thus resulting in a hike in electron velocity.

Chapter 11 Density of States, Fermi Energy and Energy Bands

Most actual band structures for semiconductors have ellipsoidal energy surfaces which require longitudinal and transverse effective masses in place of the three principal effective masses (Figure 11.3). Therefore, the density-of-states effective mass is 3 1

3/1/2017· The figure implies that the DCR doubles for every 5.3 °C increase in T. Dark counts have adverse effects on the performance of a SiPM. In a photon counting regime, DCR imposes a lower limit on a measurable photon rate and contributes to the upper limit too. In an analog (or continuous wave) operation, DCR is represented by the magnitude of
