Abstract
In a previous paper, we found that between InP and In0.52Al0.48As grow n by molecular beam epitaxy, an interface layer exists, owing to the i nteraction of arsenic with InP in the preheat phase of the MBE growth. To determine the refractive index and thicknesses of the In0.52Al0.48 As and the interface layer in the wavelength range from 300 to 1900 nm , layers 10, 20, 200 and 2000 nm thick of MBE-grown In0.52Al0.48As on InP were investigated using spectroscopic ellipsometry.
