Real-time extraction of growth rates from rotating substrates during molecular-beam epitaxy [PDF]

, 1995
We present a method for measuring molecular‐beam epitaxy growth rates in near real‐time on rotating substrates. This is done by digitizing a video image of the reflection high‐energy electron diffraction screen, automatically tracking and measuring the ...
