Real-time Monitoring ToolsThe MBE growth can be monitored in real-time using a Reflective High Energy Electron Diffraction (RHEED) system. The system includes an electron gun which directs an electron beam towards the substrate at a shallow angle (1-2°), and a phosphor screen which detects the diffracted beam.
As the substrate surface varies (from rough to smooth) so does the pattern detected at the screen.
