ABSTRACT

The present proposal focuses on theoretical and experimental on-site electronic and atomic-structural characterization of nano-diamond (nD) and nano SiC doped high phase-transition temperature (Tc) superconducting (HTSC) diboride (HTSCD) MgB2 nanocomposite cluster’s single crystal and thin films by using the element specific and local structure sensitive soft resonant MgK/L and BK X-ray absorption edge (XAE) fine structure (XAFS) spectroscopic ideal probe to give potential HTSC properties of nanoparticle carbon embedded in the matrix of nanocomposite borides to drive and to develop high performance doped MgB2 phase with amplified Tc.

Keywords : Tc, HTSC, HTSCD, Nanodiamond (nD), NanoSiC, XAFS, XAS.
