ABSTRACT
This letter describes a parameter-free, simulation-free route to predict dopant-defect energetics under given hydrostatic strained silicon lattices using readily available physical constants such as electronegativity and size, and dimensionless correlations derived from density functional theory calculations. Illustration of the effectiveness of these correlations to predict the behavior of dopant materials is shown for strained SiGe materials. As a more stringent test of the reliability of the correlations and their ability to extend beyond the SiGe materials, we also demonstrate the accuracy of these correlations for the prediction of dopant energetics for other classes of electronic materials, such as the III/V material, GaAs.

    Millimeter size single crystals of double-perovskite La2NiMnO6 were grown by the high-temperature solution growth method. The magnetic measurements and polarized Raman spectra between 5 and 350 K provide evidence that the crystals have a high degree of Ni2+/Mn4+ ordering, a small amount of...

    Raman spectroscopy of (1-x) NBT-xBiCrO3 solid solutions was carried at room temperature. In addition to well known Raman modes two additional bands near 770 and 835 cm-1 were observed. The intensity of these bands increased gradually with increase in BiCrO3 concentration. Their presence was...

    We study the relative stability of two different lattice types for model polymeric solids, using a recently developed density functional theory for freely-hinged, polymeric chains of hard globular segments. The most stable crystal-lattice type appears to be determined by the mean length and the...
