In Situ and Real-Time Monitoring of Doping Levels by Reflectance Anisotropy Spectroscopy (RAS) during Molecular Beam Epitaxial (MBE) Growth of III/V Semiconductors

Figure 13

Averaged RAS spectrum of an Al0.5Ga0.5As sample (P1184, 800°C Be effusion cell temperature) with p-doping, shown in red. The spectrum for the undoped layer is shown in black. The connecting lines are only visual aids.
