High-Efficiency Power Conversion Using Silicon Carbide Power Electronics

, 2013
The message of this paper is that the silicon carbide power transistors of today are good enough to design converters with efficiencies and switching speeds beyond comparison with corresponding technology in silicon. This is the time to act.

High‐Temperature Magnetic Field Mapping Using a Single‐Crystal Diamond MEMS Resonator Array

Advanced Science, EarlyView.
A single‐crystal diamond MEMS resonator array enables magnetic‐field reconstruction with millisecond response, nanotesla level magnetic noise, and stable operation up to 573 K. Two‐ and three‐dimensional magnetic field mapping are demonstrated using ΔEeffect sensing, highlighting the potential of diamond MEMS technology for hightemperature magnetic ...

Coarsening‐Resistant Ag Sinter Composites: Mechanistic Insights From Different Ag–Additive Systems

Advanced Electronic Materials, EarlyView.
An Ag–WC sintered composite exhibiting superior resistance to thermal coarsening. Different particle‐reinforced Ag sinter composites showed markedly different microstructural responses to thermal aging. The comparison revealed that robust Ag–additive interfaces maintain grain‐boundary pinning, whereas insufficient interfacial stability results in the ...

Electrical Properties and Interfacial Strain in Thermally Oxidized 4H‐SiC MOS Structures Under Different Post‐Oxidation Annealing

Advanced Electronic Materials, EarlyView.
This work investigates the electrical properties and interfacial strain in thermally oxidized 4H‐SiC MOS structures under different post‐oxidation annealing. Nitrogen annealing simultaneously reduces interface state density and increases interfacial tensile strain, thus being accompanied by the formation of an interfacial dipole.

Nanocrystalline LCO/LLZO Composite Cathode Films for Solid State Batteries

Advanced Energy Materials, EarlyView.
A single precursor solution is solution‐deposited and calcined at only 750°C to yield a dense, nanograined LiCoO2/LLZO composite cathode, in which both phases crystallize independently with minimal interdiffusion. Assembled into all‐solid‐state Li‐metal batteries, the composite delivers 111.7 mAh g−1 initial discharge capacity and retains 93% after 100

Operation of Silicon Carbide BJTs Free from Bipolar Degradation

, 2010
The mechanisms of bipolar degradation in silicon carbide BJTs are investigated and identified. Bipolar degradation occurs as result of stacking fault (SF) growth within the low-doped collector region.

How small changes to methylated piperidinium cations impact the synthesis of zeolite SSZ‐39

AIChE Journal, EarlyView.
Abstract Here we report a synthesis study of SSZ‐39 with four different organic structure directing agents (OSDA). The goal was to determine how subtle changes to the OSDA architecture impact crystallization kinetics, material composition, and other properties.
