Epitaxial single T centres in silicon-on-insulator
Christian H. Christiansen, Kasper H. Nielsen, Alisha Nanwani +26
Spin-photon interfaces based on silicon quantum emitters offer a scalable platform for quantum computing and networking. However, achieving coherent photon emission remains a prima…
Probing of Core Excitons in Solid NaF with Polarization-Selective Attosecond Time-Resolved Four-Wave Mixing Spectroscopy
Kevin Gulu Xiong, Rafael Quintero-Bermudez, Vincent Eggers +3
Nonlinear Four-wave mixing processes are a powerful technique to unravel ultrafast dynamics in solid-state systems. Here, we employ attosecond four-wave mixing spectroscopy with on…
From interface-limited to Auger-dominated carrier dynamics in -SnS
Hugo Laurell, Kevin Xiong, Nedjma Ouahioune +10
Metastable cubic tin(II) sulfide (-SnS) is an earth-abundant semiconductor whose three-dimensionally bonded chiral lattice may overcome the short minority-carrier lifetime of o…
Coherent phonon motions and ordered vacancy compound mediated quantum path interference in Cu-poor CuInGaSe (CIGS) with attosecond transient absorption
Hugo Laurell, Jonah R. Adelman, Elizaveta Yakovleva +7
In this study, coherent phonon motion is observed in bandgap excited CuInGaSe (CIGS) utilizing extreme ultraviolet (XUV) attosecond transient absorption spectro…
Coherently Coupled Carrier and Phonon Dynamics in Elemental Tellurium Probed by XUV Transient Absorption
Jonah R. Adelman, Hugo Laurell, Lauren B. Drescher +3
The narrow bandgap semiconductor elemental tellurium (Te) has a unique electronic structure due to strong spin-orbit splitting and a lack of inversion symmetry of it's helical latt…
