Calculation of the specific heat in ultra-thin free-standing silicon membranes
E. Chávez, J. Cuffe, F. Alzina +1
The specific heat of ultra-thin free-standing membranes is calculated using the elastic continuum model. We first obtain the dispersion relations of the discrete set of acoustic mo…

Lifetimes of Confined Acoustic Phonons in Ultra-Thin Silicon Membranes
J. Cuffe, O. Ristow, E. Chávez +8
We study the relaxation of coherent acoustic phonon modes with frequencies up to 500 GHz in ultra-thin free-standing silicon membranes. Using an ultrafast pump-probe technique of a…

Direct Measurement of Room Temperature Non-diffusive Thermal Transport Over Micron Distances in a Silicon Membrane
Jeremy A. Johnson, A. A. Maznev, John Cuffe +6
The "textbook" phonon mean free path (MFP) of heat carrying phonons in silicon at room temperature is ~40 nm. However, a large contribution to the thermal conductivity comes from l…
