Persistence of Island Arrangements During Layer-by-Layer Growth Revealed Using Coherent X-rays
Guangxu Ju, Dongwei Xu, Matthew J. Highland +7
Understanding surface dynamics during epitaxial film growth is key to growing high quality materials with controllable properties. X-ray photon correlation spectroscopy (XPCS) usin…
Real-time X-ray Monitoring of the Nucleation and Growth of AlN Epitaxial Films on Sapphire (0001)
Guangxu Ju, Matthew J. Highland, Jeffrey A. Eastman +4
We report the results of x-ray scattering studies of AlN on c-plane sapphire during reactive radiofrequency magnetron sputtering. The sensitivity of in situ x-ray measurements allo…
Chrono CDI: Coherent diffractive imaging of time-evolving samples
A. Ulvestad, A. Tripathi, S. O. Hruszkewycz +4
Bragg coherent x-ray diffractive imaging is a powerful technique for investigating dynamic nanoscale processes in nanoparticles immersed in reactive, realistic environments. Its te…
