Sandia Invents Versatile High-Temperature Seebeck and Electrical Conductivity Instrument

On May 17, 2013, in Materials Science, News, News & Events, Office of Science, Research & Capabilities

Sandia post­doc Harlan Brown-Shaklee (in the Electronic, Optical, and Nanostructured Materials Dept.) and staff members Jon Ihlefeld (also in the Electronic, Optical, and Nanostructured Materials Dept.) and Peter Sharma (in the Materials Physics Dept.) have built a high-temperature Seebeck and electrical conductivity measurement instrument that can operate over broad atmosphere and temperature conditions. The Seebeck [...]

Research on topological insulators (TIs) has drawn intensive interests. The type-II InAs/GaSb heterostructure, due to its unusual alignment of the conduction and valence band edges of InAs and GaSb, is predicted to be a two-dimensional (2D) TI. Historically, type-II InAs/GaSb heterostructures have been extensively studied for infrared applications. With the new prediction as a 2D [...]

Sandia and industrial giant Caterpillar Inc. have signed their first umbrella cooperative research and development agreement (CRADA), opening the door to a wide range of scientific research. “This agreement will lead to an expanded relationship with Caterpillar,” said Vic Weiss, the Sandia business development specialist who helped negotiate the CRADA. “It’s a strategic collaboration.” The [...]


Sandia-Developed Alloy Has Potential for Electronics in Wells

On April 3, 2013, in Energy, Geothermal, Materials Science, News, News & Events, Renewable Energy, Research & Capabilities, Systems Engineering

A few years ago, researchers asked Sandia’s geothermal group to develop electronics to monitor well conditions in field operations—withstanding high temperatures and pressures, excessive vibrations, and other extreme environments. Most brazing processes occur at a peak temperature above about 700° C, while most soldering occurs below 350° C, leaving high-temperature electronics few filler materials from which to [...]


Sandia, DOE Energy Storage Program, GeneSiC Semiconductor, U.S. Army ARDEC: Ultra-High-Voltage Silicon Carbide Thyristors

Increasing consumer power demand creates numerous challenges for ensuring reliable, stable power for all customers. Many energy generation technologies, particularly renewables, generate direct-current power that must be converted to alternating current before use. Power switches, known as thyristors, perform this conversion and are crucial to a reliable electricity grid. Current switches have been inefficient and [...]
