Efficient thermionic operation and phonon isolation by a semiconductor-superconductor junction
Emma Mykkänen, Janne S. Lehtinen, Leif Grönberg +6
Control of heat flux at small length scales is crucial for numerous solid-state devices and systems. In addition to the thermal management of information and communication devices…
Traceable Coulomb Blockade Thermometry
Ossi Hahtela, Emma Mykkanen, Antti Kemppinen +6
We present a measurement and analysis scheme for determining traceable thermodynamic temperature at cryogenic temperatures using Coulomb blockade thermometry. The uncertainty of th…
Superconducting platinum silicide for electron cooling in silicon
M J Prest, J S Richardson-Bullock, Q T Zhao +7
We demonstrate electron cooling in silicon using platinum silicide as a superconductor contact to selectively remove the highest energy electrons. The superconducting critical temp…
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…
