Device contacts as spin-state selectors for silicon vacancies in 4H-SiC

Aurora Teien, Maria Mendes Martins, Andreas Gottscholl +11

Optically addressable defect spins in semiconductors are promising building blocks for scalable quantum technologies. Yet, the consequences of conventional contact schemes used in…

Muonium dynamics as a probe for depth-resolved properties of 4H-SiC

Maria Mendes Martins, Piyush Kumar, Marianne E. Bathen +5

This study establishes a baseline for muonium (Mu) charge-exchange dynamics in n-type 4H-SiC through a detailed low-energy muon spin rotation (LE-uSR) investigation. Epitaxially gr…

Observation and manipulation of charge carrier distribution at the SiO/Si interface

Maria M. Martins, Piyush Kumar, Marianne E. Bathen +3

Using low-energy muons, we map the charge carrier concentration as a function of depth and electric field across the \SiOSi interface up to a depth of \SI{100}{\nano\meter} in Si-b…

Improving the low-energy muon beam quality of the LEM beamline at PSI: Characterisation of ultra-thin carbon foils

Gianluca Janka, Maria Mendes Martins, Xiaojie Ni +3

The Low-Energy Muon beamline (LEM) at the Paul Scherrer Institute currently stands as the world's only facility providing a continuous beam of low-energy muons with keV energies fo…

Small sample measurements at the low energy muon facility of Paul Scherrer Institute

X. Ni, L. Zhou, M. M. Martins +3

The low energy muon spin rotation spectroscopy (LE-SR) is primarily used to investigate thin films, surfaces, and interfaces of materials, which has matured at the Paul Scherrer…
