Interface Structure/Surface Morphology of (Co,Fe,Ni)/Cu/Si Thin Films
25 Mar 2014 | | Contributor(s):: Brian Demczyk, R. Naik, A. Lukaszew, G. W. Auner, V. M. Naik
The effects of thin film and interfacial stress on the magnetic properties Fe, Co and Ni films deposited by molecular beam epitaxy on Cu underlayers (Si substrate) were examined, employing transmission,ans scanning probe microscopy and reflection high energy diffraction. It ws found that the...
Novel EM Nanoscale Techniques
27 Nov 2017 | | Contributor(s):: Brian Demczyk
Describes unconventional use of conventional techniques (SAD,CBED, HREM and Fourier analysis) to elucidate hard-to-access structural information at the nano scale.
Structure and Morphology of Silicon-Germanium Thin Films
07 Feb 2015 | | Contributor(s):: Brian Demczyk
This presentation describes the growth of (Si,Ge & SiGe) thin films on Si and Ge (001) and (111) substrates by ultrahigh vacuum chemical vapor deposition (UHVCVD). Thin films were characterized structurally by conventional and high-resolution transmission electron microscopy (TEM) and...
Surface structure and composition of high-surface-area molybdenum nitrides
02 Feb 2012 | | Contributor(s):: Brian Demczyk, j. G. Choi, L. T. Thompson
In this work, we have employed high-resolutiontransmission electron microscopy coupled with Fourier analysis, and X-ray photoelectron spectroscopy todetermine the near-surface structures and compositions of a series of molybdenum nitride catalysts.
