Progress and perspectives on electron-doped cuprates
Although the vast majority of high-T c cuprate superconductors are hole-doped, a small
family of electron-doped compounds exists. Underinvestigated until recently, there has been …

Speciation using X-ray absorption fine structure (XAFS)
A Gaur, BD Shrivastava - Review Journal of Chemistry, 2015 - Springer
X-ray absorption fine structure (XAFS) spectroscopy is in use as a unique fingerprinting
technique. By employing spectra of well-defined chemical species (standards), XAFS can be …

Shallow donors in diamond: chalcogens, pnictogens, and their hydrogen complexes
The utility of diamond as an electronic material is compromised by the lack of a suitable
shallow donor. Here, ab initio theory is used to investigate the donor levels of substitutional …
