Comprehensive analysis in the journal "APL Materials" provides blueprint for making thermoelectric materials that convert heat and electricity with greater efficiency WASHINGTON, July 15, 2014 /PRNewswire-USNewswire/ -- From your hot car to your warm laptop, every machine and device in your life wastes a lot of energy through the loss of heat. But thermoelectric devices, which convert heat to electricity and vice versa, can harness that wasted heat, and possibly provide the green...

University of Miami A University of Miami physicist and his collaborators find remarkable thermoelectric properties for a metal that may impact the search for materials useful in power generation, refrigeration or energy detection Thermoelectric materials can turn a temperature difference into an electric voltage. Among their uses in a variety of specialized applications: generating power on space probes and cooling seats in fancy cars. University of Miami (UM) physicist Joshua Cohn...

Nanoscale Pillars Could Radically Improve Thermoelectric Materials
2014-02-21 13:46:23

University of Colorado at Boulder University of Colorado Boulder scientists have found a creative way to radically improve thermoelectric materials, a finding that could one day lead to the development of improved solar panels, more energy-efficient cooling equipment, and even the creation of new devices that could turn the vast amounts of heat wasted at power plants into more electricity. The technique—building an array of tiny pillars on top of a sheet of thermoelectric...

Researchers Find Clear Evidence For Coherent Phonons In Superlattices
2014-02-06 13:20:27

Berkeley Lab We all learn in high school science about the dual nature of light – that it exists as both waves and quantum particles called photons. It is this duality of light that enables the coherent transport of photons in lasers. Sound at the atomic-scale has the same dual nature, existing as both waves and quasi-particles known as phonons. Does this duality allow for phonon-based lasers? Some theorists say yes, but the point has been argued for years. Recently a large...

Caged Atoms Used To Create Electricity

Vienna University of Technology At the Vienna University of Technology, a new class of thermoelectric materials has been discovered; Due to a surprising physical effect they can be used to create electricity more efficiently A lot of energy is wasted when machines turn hot, unnecessarily heating up their environment. Some of this thermal energy could be harvested using thermoelectric materials; they create electric current when they are used to bridge hot and cold objects. At the Vienna...

A new study published today in the journal Nature Materials has found a way to suppress the thermal conductivity in sodium cobaltate so that it can be used to harvest waste energy. Led by scientists at Royal Holloway University, the team conducted a series of experiments on crystals of sodium cobaltate grown in the University's Department of Physics. X-ray and neutron scattering experiments were carried out at the European Synchrotron Radiation Facility and in the Institut Laue-Langevin in...

Researchers Discover Novel Material For Cooling Of Electronic Devices
2013-07-29 10:57:48

U.S. Naval Research Laboratory A team of theoretical physicists at the U.S. Naval Research Laboratory (NRL) and Boston College has identified cubic boron arsenide as a material with an extraordinarily high thermal conductivity and the potential to transfer heat more effectively from electronic devices than diamond, the best-known thermal conductor to date. As microelectronic devices become smaller, faster, and more powerful, thermal management is becoming a critical challenge. This work...
