Abstract: We propose and analyze a simple variational model for dislocations at semi-coherent interfaces. The energy functional describes the competition between two terms: a surface energy induced by dislocations and a bulk elastic energy, spent to… read more here.

Abstract: Abstract In this work, we have systematically explored the atomic structure, adhesion work, interfacial energy and fracture mechanism of the semi-coherent Al(1 1 1)/Al3BC(0001) interface using the first-principles calculations. The relaxed atomic structure reveals that the MT… read more here.

DOI: 10.1016/j.scriptamat.2018.09.018
Abstract: Abstract Designing low-energy interface structures is crucial in growth and coarsening studies of Al2Cu (θ′) precipitates. Given new experimental insights into the θ′/Al system, we use Density Functional Theory (DFT) calculations to investigate the energetics… read more here.

DOI: 10.1109/tvt.2018.2868856
Abstract: This work presents the exact symbol error rate (SER) analysis of semi-coherent demodulated systems in the presence of imperfect knowledge of the channel estimates. The SER is derived in the context of orthogonal frequency division… read more here.
