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…
Sub-wavelength mid-infrared imaging of locally driven photocurrents using diamond campanile probes
Rajasekhar Medapalli, Nathan D. Cottam, Khushboo Agarwal +12
Precise and high efficiency concentration of mid-infrared (mid-IR) light into sub wavelength volumes is essential for probing low-energy excitations and achieving strong field enha…
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…
FIR transmission and resistively detected cyclotron resonances in InSb
M. E. Bal, N. DeÃmann, K. Saeedi +1
We have developed an experimental setup to simultaneously acquire magneto-transmission spectra and measure the photoconductive response. The low-temperature (=4.2 K) magneto-tra…
Photon Echo in Uniaxially Stressed Germanium with Antimony Donors
R. Kh. Zhukavin, V. D. Kukotenko, P. A. Bushuykin +8
Photon echo is observed in n-type Ge uniaxially stressed along the [111] crystallographic direction, with a coherence relaxation time of 300 ps. The nonlinear polarization responsi…
