摘要

对预合成物质在真空中开放蒸发制备的Pb0.9Cd0.1Te:Pb (3at .%)薄膜的表面形貌进行了分析。分析了表面晶粒的定量组成和尺寸。薄膜具有均匀的成分和颗粒结构，单个晶粒尺寸为几十微米。由于CdTe和PbTe的晶体结构不同，镉的引入是基体PbTe中晶界等缺陷形成的原因。

Surface Morphology and Growth Mechanisms of Pb-Cd-Te Thin Films

The analysis of the surface morphology of Pb0.9Cd0.1Te:Pb (3 at.%) thin films obtained by the open evaporation in vacuum from pre-synthesized substances are performed. The quantitative composition and sizes of grains on the surface were analyzed. The films have a homogeneous composition and granular structure with individual grain sizes of several tens of micrometers. The introduction of Cadmium into the base matrix PbTe is the cause of the formation of defects such as grain boundaries due to the differ between crystal structure of CdTe and PbTe.
