Kinetics of electron-phonon scattering in silicon resolved by Rydberg transitions of donors
Nils Dessmann, Aidan G. McConnell, Sergey G. Pavlov +6
Rydberg states of atoms in vacuum are now well recognized as a resource for quantum technologies. Donors in semiconductors also display analogous states, which have been proposed f…
Strong electron-electron interactions in a dilute weakly-localized metal near a metal-to-insulator transition
Nicolò D'Anna, Jamie Bragg, Aidan G. McConnell +12
Because it is easily switched from insulator to metal either via chemical doping or electrical gating, silicon is at the core of modern information technology and remains a candida…
Element-specific, non-destructive profiling of layered heterostructures
Nicolò D'Anna, Jamie Bragg, Elizabeth Skoropata +16
Fabrication of semiconductor heterostructures is now so precise that metrology has become a key challenge for progress in science and applications. It is now relatively straightfor…
Non-destructive X-ray imaging of patterned delta-layer devices in silicon
Nicolò D'Anna, Dario Ferreira Sanchez, Guy Matmon +11
The progress of miniaturisation in integrated electronics has led to atomic and nanometre-sized dopant devices in silicon. Such structures can be fabricated routinely by hydrogen r…
All-optical control of second-harmonic generation in -BaBO via coherent, terahertz-driven acentric lattice displacement
Flavio Giorgianni, Nicola Colonna, Gabriel Nagamine +6
Dynamical control of the nonlinear optical properties of solids -- with light itself -- will be essential for future ultrafast photonic technologies. Previously, methods to modulat…
Profiling THz Beams With Off-Label Use of Infrared Microbolometric Cameras
Gabriel Nagamine, Carlo Vicario, Tariq Leinen +6
Visualizing the spatial profile of light beams is essential for evaluating irradiance, characterizing beam quality, and achieving precise alignment. In the optical spectral range,…
Metrology of Complex Refractive Index for Solids in the Terahertz Regime Using Frequency Domain Spectroscopy
Steven Chick, Ben Murdin, Guy Matmon +1
Frequency domain spectroscopy allows an experimenter to establish optical properties of solids in a wide frequency band including the technically challenging 10 THz region, and in…
2D-3D crossover in a dense electron liquid in silicon
Guy Matmon, Eran Ginossar, Byron J. Villis +9
Doping of silicon via phosphene exposures alternating with molecular beam epitaxy overgrowth is a path to Si:P substrates for conventional microelectronics and quantum information…
Rapid high-temperature initialisation and readout of spins in silicon with 10 THz photons
Aidan G. McConnell, Nils Dessmann, Wojciech Adamczyk +6
Each cycle of a quantum computation requires a quantum state initialisation. For semiconductor-based quantum platforms, initialisation is typically performed via slow microwave pro…
