Revised crystal structure and electronic properties of high dielectric Ba(FeNb)O ceramics
Rajyavardhan Ray, A. K. Himanshu, Golak K. Mandal +7
Ba(FeNb)O (BFN) ceramics are considered to be promising for technological applications owing to their high dielectric constant over a wide range of temperatures…
Optical and Electronic Properties of Double Perovskite Ba2ScSbO6
Rajyavardhan Ray, A K Himanshu, Uday Kumar +4
Ba2ScSbO6 (BSS) has been synthesized in polycrystalline form by solid state reaction. Structural characterization of the compound was done through X-ray diffraction (XRD) followed…
The freezing tendency towards 4-coordinated amorphous network causes increase in heat capacity of supercooled Stillinger-Weber silicon
Pankaj A. Apte, Nandlal Pingua, Arvind Kumar Gautam +4
The supercooled liquid silicon, modeled by Stillinger-Weber potential, shows anomalous increase in heat capacity , with a maximum value close to 1060 K at zero pressure.…
