Point Defects and Localized Excitons in 2D WSe2
Yu Jie Zheng, Yifeng Chen, Yu Li Huang +8
Identifying the point defects in 2D materials is important for many applications. Recent studies have proposed that W vacancies are the predominant point defect in 2D WSe2, in cont…

Temperature-dependent dielectric function of bulk SrTiO: Urbach tail, band edges, and excitonic effects
Pranjal Kumar Gogoi, Daniel Schmidt
We report the temperature-dependent complex dielectric function of pristine bulk SrTiO between 4.2 and 300 K within the energy range of 0.6-6.5 eV determined by spectroscopic e…
