摘要
通过在真空中连续沉积 Cu 和 As2Se3，在形成 Cu/As Se 薄膜结构的过程中，Cu 扩散到 As2Se3 薄膜中，从而首次合成了等离子体纳米结构。利用光谱椭偏仪获得了合成结构在 240-2500 纳米波长范围内的消光系数和折射率光谱，以及介电常数的实部和虚部，这表明存在局部表面等离子体共振。结果表明，在波长为 470 至 660 纳米的范围内，等离子体共振的频率位置可以通过改变铜膜厚度和退火来控制。
Local Surface Plasmon Resonances in Cu/As2Se3 Film Structures
Plasmon nanostructures are synthesized for the first time as a result of Cu diffusion into an As2Se3 film during the formation of a Cu/As Se film structure by the successive deposition of Cu and As2Se3 in vacuum. Using spectroscopic ellipsometry, the spectra of the extinction coefficients and refractive index, as well as the real and imaginary parts of the permittivity of the synthesized structures in the wavelength range of 240–2500 nm, that indicate the presence of localized surface plasmon resonances are obtained. It is shown that the frequency position of plasmon resonances in the wavelength range from 470 to 660 nm can be controlled by changing the thickness of the copper film and annealing.
