Figure 8. The optical properties of the germanane/siloxene heterostructure. (A) Calculated energy curve of germanane/siloxene as a function of interlayer distance. (B and C) represent the optical absorption coefficient α of the isolated germanane and siloxene layers and the germanane/siloxene heterostructure in the x and y directions, respectively. (D) Comparison of the optical absorption coefficient α of germanane/siloxene in the x and y directions.
