Abstract

We present the composition engineering and Raman scattering study of Bi₂Se_3xTe_3(1-x) nanoplates that were synthesized by chemical vapor deposition method using different substrates, including fluorophlogopite mica, SiO₂/Si. The characterizations revealed high crystallinity and layered-structure in the ternary Bi₂Se_3xTe_3(1-x) products. Raman spectra of Bi₂Se_3xTe_3(1-x) ranging from 80-200 cm^-1 as a function of different Se-doping levels shows that intrinsic Raman peaks of Bi₂Se_3xTe_3(1-x) nanoplates shift to higher frequency as the ratio of doped-Se increasing. The discontinuity of Raman peaks was found and discussed.
