Strain enhanced electron cooling in a degenerately doped semiconductor
M. J. Prest, J. T. Muhonen, M. Prunnila +9
Enhanced electron cooling is demonstrated in a strained-silicon/superconductor tunnel junction refrigerator of volume 40 um^3. The electron temperature is reduced from 300 mK to 17…

Strain control of electron-phonon energy loss rate in many-valley semiconductors
J. T. Muhonen, M. J. Prest, M. Prunnila +8
We demonstrate significant modification of the electron-phonon energy loss rate in a many-valley semiconductor system due to lattice mismatch induced strain. We show that the therm…
