Report by BC Professor of Physics David Broido and international colleagues confirm high thermal conductivity predicted for isotopically enriched cubic boron nitride Research by Professor of Physics ...

Buildings often feel too warm in the summer and too cold in the winter. In the summer, energy transfers to the building from its warmer surroundings. In winter, energy transfers from the building ...

The crucial insight is that the phonons that are responsible for the lattice component of the thermal conductivity typically have longer mean free paths than the electrons in thermoelectric materials.
