摘要

采用封闭空间升华（CSS）法制备了碲化锌（ZnTe）薄膜。研究了浓磷酸化学处理对薄膜光学、电学和结构性能的影响。通过x射线衍射（XRD）光谱证实了薄膜的多晶性质的锌共混物结构。能量色散x射线（EDX）显示，当暴露于磷酸时，膜表面上的Te比率增加。此外，薄膜的直流电阻率显著下降。膜的折射率、厚度和厚度不规则性通过拟合400至2500nm波长范围内的透光光谱来确定。还报道了处理对光学参数的影响。

Effect of phosphoric acid treatment on the physical properties of zinc telluride thin films

Zinc Telluride (ZnTe) films were prepared by the closed space sublimation (CSS) method. The effect of chemical treatments with concentrated phosphoric acid, on the optical, electric and structural properties of the films was studied. Zinc-blend structure of the polycrystalline nature of the films was confirmed by x-ray diffraction (XRD) spectra. The energy dispersive x-ray (EDX) shows an increase in Te ratio on the surface of the film as exposed to phosphoric acid. In addition, the dc electrical resistivity of the films was dropped considerably. The refractive index, thickness, and thickness irregularity of the films were determined by fitting of the optical transmittance spectra in the wavelength range 400 to 2500 nm. The effect, of treatment, on the optical parameters is also reported.

期刊介绍： Chalcogenide Letters (CHL) has the aim to publish rapidly papers in chalcogenide field of research and appears with twelve issues per year. The journal is open to letters, short communications and breakings news inserted as Short Notes, in the field of chalcogenide materials either amorphous or crystalline. Short papers in structure, properties and applications, as well as those covering special properties in nano-structured chalcogenides are admitted.
