Titel:
Helium Ion Modified Luminescence and Robust Valley Polarization of Atomically Thin MoS2 
Abstract:
We show a systematic study of the impact of focused helium ions on the optical, vibrational, and valleytronic properties of atomically thin MoS2. The shifting of the first-order Raman modes are explained by a phonon confinement model introducing an effective interdefect distance. We perform ab-initio density functional theory calculations on a variety of defect related morphologies to explain an additional luminescence peak by O2 molecules chemisorbed at monosulphur vacancies. We further obs...    »
