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…
Dispersive readout of reconfigurable ambipolar quantum dots in a silicon-on-insulator nanowire
Jingyu Duan, Janne S. Lehtinen, Michael A. Fogarty +8
We report on ambipolar gate-defined quantum dots in silicon on insulator (SOI) nanowires fabricated using a customised complementary metal-oxide-semiconductor (CMOS) process. The a…
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…
Thermoelectric bolometers based on ultra-thin heavily doped single-crystal silicon membranes
Andrey V. Timofeev, Aapo Varpula, Andrey Shchepetov +5
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.…
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…
Ultra-Thin Free-Standing Single Crystalline Silicon Membranes With Strain Control
Andrey Shchepetov, Mika Prunnila, Francesc Alzina +6
We report on fabrication and characterization of ultra-thin suspended single crystalline flat silicon membranes with thickness down to 6 nm. We have developed a method to control t…
Phonons in Slow Motion: Dispersion Relations in Ultra-Thin Si Membranes
John Cuffe, Emigdio Chavez, Andrey Shchepetov +11
We report the changes in dispersion relations of hypersonic acoustic phonons in free-standing silicon membranes as thin as \sim 8 nm. We observe a reduction of the phase and group…
