Abstract
This chapter presents an introduction to superconductor-semiconductor (S-Sm) tunnel junction coolers, before outlining some of the progresses made during the nanofunction program on electron cooling from 300 mK in silicon-based junctions. PtSi is an interesting material to consider as a Schottky barrier to Si because of its role as a contact material in the semiconductor industry. The chapter investigates carrier-phonon coupling in unstrained silicon, with both n- and p-type dopants, and the effect of increasing the strain in silicon grown on a Si1–xGex virtual substrate with the Ge fraction x of 20% and 30%. The reduction in e-ph coupling shows promise for dramatic improvements in performance of bolometric detectors for a variety of electromagnetic radiation sensing applications using silicon based cold electron bolometers.
