▎ 摘  要

NOVELTY - Preparing single crystal graphene/two-dimensional cuprous telluride heterojunction surface-enhanced Raman spectroscopy substrate comprises (i) preparing copper film on the sapphire substrate by direct current magnetron sputtering method; (ii) covering the copper film obtained by an envelope type and preparing single-crystal graphene by using chemical vapor deposition; and (iii) etching the single crystal graphene copper substrate prepared in 0.5 mol/liter iron chloride solution for roughening the prepared single crystal graphene/copper substrate. USE - The method is useful for preparing single crystal graphene/two-dimensional cuprous telluride heterojunction surface-enhanced Raman spectroscopy substrate is useful in surface-enhanced Raman spectroscopy (claimed). ADVANTAGE - The method: can be mass-produced without transfer; and produces the heterojunction surface-enhanced Raman spectroscopy substrate significantly enhances the signal of the detected probe molecule with high reproducibility. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: Single crystal graphene/two-dimensional cuprous telluride heterojunction surface-enhanced Raman spectroscopy substrate, prepared as mentioned above; and Application of single crystal graphene/two-dimensional cuprous telluride heterojunction surface-enhanced Raman spectroscopy substrate in surface-enhanced Raman spectroscopy.
