You are teaching a surface science class and are on the topic of RHEED, and you’d like the students to check the ratio of lattice spacings along different crystal directions to verify the bcc structure of a material.You are working with SrTiO3 substrates, and you’d like to compare your RHEED patterns to those other researchers in your field are checking, for example, the width and length of the diffraction streaks as an indication of surface quality.

You’re curious about what the oxide desorption process looks like for a GaAs substrate, so you load a GaAs desorb movie from the RIL and watch the evolution of the RHEED pattern as the oxide desorption occurs.Here are some examples of how we envision the RIL being used: We envision the use of the RIL to be mainly as a reference library for RHEED. These details are either in the file name or in the Comments section of the file
what the growth conditions are (temperature substrate, etc.), what the crystal orientation is, what the beam energy is, and so on. We have asked our customers to document the details of the conditions under which the data was taken, e.g. The kSA 400 RHEED Image Library (RIL) is a compilation of images and movies acquired from our kSA 400 customers, to the tune of ~ 30 gbytes of data.
