Metric-wave approach to flexoelectricity within density-functional perturbation theory
Andrea Schiaffino, Cyrus E. Dreyer, David Vanderbilt +1
Within the framework of density functional perturbation theory (DFPT), we implement and test a novel "metric wave" response-function approach. It consists in the reformulation of a…
Defect identification based on first-principles calculations for deep level transient spectroscopy
Darshana Wickramaratne, Cyrus E. Dreyer, Bartomeu Monserrat +4
Deep level transient spectroscopy (DLTS) is used extensively to study defects in semiconductors. We demonstrate that great care should be exercised in interpreting activation energ…
Current-density implementation for calculating flexoelectric coefficients
Cyrus E. Dreyer, Massimiliano Stengel, David Vanderbilt
The flexoelectric effect refers to polarization induced in an insulator when a strain gradient is applied. We have developed a first-principles methodology based on density-functio…
