Wafer-scale graphene field-effect transistor biosensor arrays with monolithic CMOS readout
Miika Soikkeli, Anton Murros, Arto Rantala +11
The reliability of analysis is becoming increasingly important as point-of-care diagnostics are transitioning from single analyte detection towards multiplexed multianalyte detecti…
Thermal transport in nanoelectronic devices cooled by on-chip magnetic refrigeration
S. Autti, F. C. Bettsworth, K. Grigoras +8
On-chip demagnetization refrigeration has recently emerged as a powerful tool for reaching microkelvin electron temperatures in nanoscale structures. The relative importance of coo…
Scalable on-chip multiplexing of silicon single and double quantum dots
Heorhii Bohuslavskyi, Alberto Ronzani, Joel Hätinen +5
Owing to the maturity of complementary metal oxide semiconductor (CMOS) microelectronics, qubits realized with spins in silicon quantum dots (QDs) are considered among the most pro…
Interplay of electron and phonon channels in the refrigeration through molecular junctions
Fatemeh Tabatabaei, Samy Merabia, Bernd Gotsmann +2
Due to their structured density of states, molecular junctions provide rich resources to filter and control the flow of electrons and phonons. Here we compute the out of equilibriu…
Microkelvin electronics on a pulse-tube cryostat with a gate Coulomb blockade thermometer
Mohammad Samani, Christian P. Scheller, Nikolai Yurttagül +8
Access to lower temperatures has consistently enabled scientific breakthroughs. Pushing the limits of \emph{on-chip} temperatures deep into the microkelvin regime would open the do…
Dispersive readout of reconfigurable ambipolar quantum dots in a silicon-on-insulator nanowire

We present ultra-thin silicon membrane thermocouple bolometers suitable for fast and sensitive detection of low levels of thermal power and infrared radiation at room temperature.…
On-chip magnetic cooling of a nanoelectronic device
D. I. Bradley, A. M. Guénault, D. Gunnarsson +8
We demonstrate significant cooling of electrons in a nanostructure below 10 mK by demagnetisation of thin-film copper on a silicon chip. Our approach overcomes the typical bottlene…
Nanoelectronic thermometers optimised for sub-10 millikelvin operation

We report the cooling of electrons in nanoelectronic Coulomb blockade thermometers below 4 mK. Above 7 mK the devices are in good thermal contact with the environment, well isolate…
Reconstructing phonon mean free path contributions to thermal conductivity using nanoscale membranes
John Cuffe, Jeffery K. Eliason, Alexei A. Maznev +8
Knowledge of the mean free path distribution of heat-carrying phonons is key to understanding phonon-mediated thermal transport. We demonstrate that thermal conductivity measuremen…
