Abstract In this work, we demonstrate a simple technique to grow high-quality whiskers of Bi2 Sr2 CaCu2 O8+δ – a high T c superconductor. Structural analysis shows the single-crystalline nature of the grown whiskers. To probe electrical properties

The influence of the underlying nucleation layer on the properties of semipolar $$(11{\bar{2}}2)$$ GaN grown on m-plane sapphire by metalorganic vapor-phase epitaxy has been investigated. $$(11{\bar{2}}2)$$ GaN epilayers of ~ 1 μm thickness were gro

We report an ohmic contact metallization scheme for n-GaN based on a Re–Al–Ni–Au multilayer stack that offers low-resistivity and provides better edge sharpness and lower surface roughness at reduced annealing temperature compared to standard T

Using the hexagonal → cubic transition in Ag as a prototype, we provide a simple, mechanistic model for a large class of irreversible solid–solid structural transformations. Our conclusions are based on a detailed study of the effects of spatial

In this work, we showed the tuning of the catalytic behavior of dendritic plasmonic colloidosomes (DPCs) by plasmonic hotspots. A cycle-by-cycle solution-phase synthetic protocol yielded high-surface-area DPCs by controlled nucleation–growth of gol

To accentuate the role of pn heterojunctions in composites, the photocatalytic properties of two composites NTC11 (NiO and TiO 2 in 1:1 molar ratio) and NTC36 (0.35:0.65) were investigated in detail for H 2 evolution reaction and compared with the co

The transformation between the metallic ( β ) and semiconducting ( α ) allotropes of tin is still not well understood. The phase transition temperature stated in the literature, 286.2 K, seems to be inconsistent with recent calorimetric measurement

In this paper, we study the structure of the solid selenium (Se) formed by the vapor deposition method. We provide direct visual evidence that faceted crystal-like shapes obtained from vapor phase deposition are a self-assembly of linear strands that

The combination of ultrasmall nanoparticles and pseudo-single atoms of gold (Au) and fibrous nanosilica (KCC-1) functionalized with 3-aminopropyltriethoxysilane (APTS) enabled the design of KCC-1-APTS/Au nanocatalysts with very high turnover numbers
