Abstract
This chapter discusses the cooling of a platform, which
requires the electronic coolers to extract heat by
coupling to phonons within the platform material. Major
results obtained within the nanofunction NoE on the
development of nanomodulated magnetic materials and the
investigation of their main properties are also
presented. The cooling power of the devices becomes
paramount, as opposed to the base temperature that could
be reached, and must exceed heat leaks into the platform
from the surroundings. This indirect cooling is desirable
for systems where electrical isolation from the
refrigeration elements is required, such as in quantum
information applications or superconducting transition
edge sensors (TESs). Thick porous Si layers on the Si
wafer constitute alternative structures that could
replace the rather fragile silicon nitride membranes for
use as thermal isolation platforms. The structure and
morphology of porous Si determines its electrical and
thermal conductivity.
