Title:
Helium ion modified luminescence and valley depolarization of atomically thin MoS2 
Abstract:
We show a systematic study of the impact of disorder on the optical properties and intervalley scattering of atomically thin MoS2. Using a helium ion microscope (HIM) we induce defects in the crystal lattice. Optical analysis reveals significant shifts of both first order Raman modes E’ and A1 which are well explained by phonon confinement due to increasing disorder linking the ion dose to the inter-defect distance. Low-temperature (T=10K) confocal micro-photoluminescence (µ-PL) exhibits additio...    »
