摘要
A CCD-based, computer controlled RHEED detection and analysis system that utilizes an on-chip integration technique and on-board data manipulation is described. The system is capable of in situ time-resolved measurements of specular and integral-order intensity oscillations, their phase differences, streak linewidths, and epitaxial layer lattice constants. The digital RHEED techniques are described in the context of Co/Au bilayer, GaAs/GaAs, and In(x)Ga(1-x)As/GaAs MBE growth. The system is compared to other RHEED detection devices.
