In summary, pristine and Yb-doped monolayer WS2 triangles are successfully fabricated via in-situ CVD technique. The samples are systematically characterized by OM, AFM, SEM and TEM for microscopic analysis. Raman, XRD, and XPS spectra are measured on both of the pristine and Yb doped WS2 for contrast to confirm the successful Yb doping. EDS in SEM and TEM are performed to evaluate the Yb ion concentration in the WS2 matrix. Three times of PL intensities accompanied with 5.6 nm of red-shifts in

摘要：

The study of rare-earth (RE) doping in two-dimensional (2D) transition metal dichalcogenides (TMDCs) has become an important research focus to modulate bandgaps and carriers for production of the exotic properties. Herein, approximately 7 at% of Yb substitutionally doped monolayer WS2 nanosheets are prepared by in-situ chemical vapor deposition (CVD) technique. Highly enhanced optical and electrical properties are obtained: Three times enhancement in photoluminescent intensities and 5.6 nm of red-shifts in wavelength are observed from their peaks after chemical doping. First-principles calcula...
