Abstract Surface morphology of InAs1-x-ySbxPy epilayers grown by liquid phase epitaxy has been studied, which has two typical patterns: crosshatch pattern and shiny uniform pattern, depending on the lattice mismatch between the epilayer and the substrate. Two kinds of micro-defects of globules and hillocks appear in the above two patterns. Although lower temperature growth can eliminate both globules and hillocks, it also brings a problem that the band gap of InAs1-x-ySbxPy alloy is not high due to the low P composition. Our study shows that globules and hillocks have no effects on the crystalline quality and compositional uniformity of InAs1-x-ySbxPy epilayers.

液相外延生长的 InAs1-x-ySbxPy 外延层的表面形貌研究
摘要 研究了液相外延生长的 InAs1-x-ySbxPy 外延层的表面形貌,根据外延层和衬底之间的晶格失配,其具有两种典型的图案:交叉影线图案和闪亮均匀图案。上述两种模式中出现了小球状和小丘状两种微缺陷。虽然较低的温度生长可以消除小球和小丘,但也带来了 InAs1-x-ySbxPy 合金由于 P 成分低导致带隙不高的问题。我们的研究表明,小球和小丘对 InAs1-x-ySbxPy 外延层的结晶质量和成分均匀性没有影响。
