Samira Dorri

PhD student

My research focuses on synthesizing and characterization of multilayers, superlattices, and superlattice supermirrors of transition metal diborides for applications in Neutron Optics.

I am a PhD student at the Swedish Graduate School in Neutron Scattering (SwedNess).

Synthesizing multilayers and artificial superlattices using DC magnetron sputtering epitaxy where I can manipulate the growth in the atomic scale is the focus of my research. I apply different characterization techniques such as XRD, XRR, TEM, XPS, ToF-ERDA, RBS, and NR to achieve an in-depth study of the crystalline quality of the structure and the degree of coherency at the interfaces.
