2 unusual facts about thermal conductivity


Conductance

Thermal conductivity, the ability for temperatures to transmit through materials

Thermal conductivity

Similar arguments were subsequently generalized to many glass forming substances using Brillouin scattering.


Drude model

This simple classical Drude model provides a very good explanation of DC and AC conductivity in metals, the Hall effect, and thermal conductivity (due to electrons) in metals near room temperature.

Isotopically pure diamond

The 12C isotopically pure, (or in practice 15-fold enrichment of isotopic number, 12 over 13 for carbon) diamond gives a 50% higher thermal conductivity than the already high value of 900-2000 W/(m·K) for a normal diamond, which contains the natural isotopic mixture of 98.9% 12C and 1.1% 13C.

Their honeymoon trip to the United States included a stint doing research on thermal conductivity of type-II superconductors and metals with Bernie Serin at Rutgers University in New Jersey.

Power electronic substrate

The FR-4-based dielectric is usually thin (about 100 μm) because it has poor thermal conductivity compared to the ceramics used in DBC substrates.

Thermal insulation

Low thermal conductivity is equivalent to high insulating capability (R-value).
