Thermal conductivity reduction due to phonon geometrical scattering in nano-engineered epitaxial germanium
Jessy Paterson, Sunanda Mitra, Yanqing Liu +7
Nano-engineering crystalline materials can be used to tailor their thermal properties. By adding new nanoscale phonon scattering centers and controlling their size, one can effecti…
Measurement of anisotropic thermal conductivity of a dense forest of nanowires using the 3 method
Dhruv Singhal, Jessy Paterson, Dimitri Tainoff +7
The 3 method is a dynamic measurement technique developed for determining the thermal conductivity of thin films or semi-infinite bulk materials. A simplified model is often app…
Network of thermoelectric nanogenerators for low power energy harvesting
Dimitri Tainoff, Anaïs Proudhom, Céline Tur +5
We report the design, elaboration and measurements of an innovative planar thermoelectric (TE) devices made of a large array of small mechanically suspended nanogenerators (nanoTEG…
Reduction of phonon mean free path: from low temperature physics to room temperature applications in thermoelectricity
Olivier Bourgeois, Dimitri Tainoff, Adib Tavakoli +5
It has been proposed for a long time now that the reduction of the thermal conductivity by reducing the phonon mean free path is one of the best way to improve the current performa…
Specific heat measurement of thin suspended SiN membrane from 8 K to 300 K using the 3-Vlklein method
Hossein Ftouni, Dimitri Tainoff, Jacques Richard +4
We present a specific heat measurement technique adapted to thin or very thin suspended membranes from low temperature (8 K) to 300 K. The presented device allows the measurement o…
The thermal conductivity of silicon nitride membranes is not sensitive to stress
Hossein Ftouni, Christophe Blanc, Dimitri Tainoff +6
We have measured the thermal properties of suspended membranes from 10 K to 300 K for two amplitudes of internal stress (about 0.1 GPa and 1 GPa) and for two different thicknesses…
