Spectral Fingerprints of Resonant Defect Scattering by Substitutional Mn in Graphene
Ahmed Samir Lotfy, Zviadi Zarkua, Renan Villarreal +10
Using substitutional Mn in graphene/Cu(111) as a model point defect, we combine scanning tunneling microscopy (STM) and angle-resolved photoemission spectroscopy (ARPES) to test th…
Exploring - and -decay-induced quenching of the Th nuclear-clock isomer in solid-state hosts
Y. Elskens, M. Athanasakis-Kaklamanakis, S. Arasada Pradeep +52
The radiative decay dynamics of an ensemble of Th nuclei embedded in CaF and MgF is investigated. The isomer is populated through decay of Ac…
Observation of the radiative decay of the nuclear clock isomer
Sandro Kraemer, Janni Moens, Michail Athanasakis-Kaklamanakis +32
The nucleus of the radioisotope thorium-229 (Th) features an isomer with an exceptionally low excitation energy that enables direct laser manipulation of nuclear states.…
Magnesium-vacancy optical centers in diamond
Emilio Corte, Greta Andrini, Elena Nieto Hernández +18
We provide the first systematic characterization of the structural and photoluminescence properties of optically active defect centers fabricated upon implantation of 30-100 keV Mg…
Towards surface diffusion potential mapping on atomic length scale
Renan Villarreal, Christopher J. Kirkham, Alessandro Scarfato +2
The surface diffusion potential landscape plays an essential role in a number of physical and chemical processes such as self-assembly and catalysis. Diffusion energy barriers can…
Structure of self-assembled Mn atom chains on Si(001)
R. Villarreal, M. Longobardi, S. A. Köster +3
Mn has been found to self-assemble into atomic chains running perpendicular to the surface dimer reconstruction on Si(001). They differ from other atomic chains by a striking asymm…
Magnetic Phase Diagram of CuO
R. Villarreal, G. Quirion, M. L. Plumer +3
High resolution ultrasonic velocity measurements have been used to determine the temperature -- magnetic-field phase diagram of the monoclinic multiferroic CuO. A new transition at…
