Discovering electron transfer driven changes in chemical bonding in lead chalcogenides (PbX, where X = Te, Se, S, O)
S. Maier, S. Steinberg, Y. Cheng +8
Understanding the nature of chemical bonding in solids is crucial to comprehend the physical and chemical properties of a given compound. To explore changes in chemical bonding in…
On the Nature of Localization in Ti doped Si
Yi Zhang, R. Nelson, K. -M. Tam +7
Intermediate band semiconductors hold the promise to significantly improve the efficiency of solar cells, but only if the intermediate impurity band is metallic. We apply a recentl…
Towards a quantitative description of tunneling conductance of superconductors: application to LiFeAs
A. Kreisel, R. Nelson, T. Berlijn +11
Since the discovery of iron-based superconductors, a number of theories have been put forward to explain the qualitative origin of pairing, but there have been few attempts to make…
Impact of Iron-site defects on Superconductivity in LiFeAs
Shun Chi, Ramakrishna Aluru, Udai Raj Singh +10
In conventional s-wave superconductors, only magnetic impurities exhibit impurity bound states, whereas for an s+- order parameter they can occur for both magnetic and non-magnetic…
Generalized Multiband Typical Medium Dynamical Cluster Approximation: Application to (Ga,Mn)N
Yi Zhang, R. Nelson, Elisha Siddiqui +7
We generalize the multiband typical medium dynamical cluster approximation and the formalism introduced by Blackman, Esterling and Berk so that it can deal with localization in mul…
What is the valence of Mn in GaMnN?
Ryky Nelson, Tom Berlijn, Juana Moreno +2
We investigate the current debate on the Mn valence in GaMnN, a diluted magnetic semiconductor (DMSs) with a potentially high Curie temperature. From a first-principles…
