Elastic modulus and resonance behavior of boron nitride nanotubes
The effective elastic modulus (E) of boron nitride nanotubes (BNNTs) was measured using the electric-field-induced resonance method inside a transmission electron microscope. The average value of E
Self-organized nanocolumnar structure in superhard TiB2 thin films
TiB2 thin films are well known for their high hardness which makes them useful for wear-resistant applications. Overstoichiometric TiB2 deposited at 300 °C by nonreactive sputtering has been shown to
Effect of temperature on growth and structure of carbon nanotubes by chemical vapor deposition
Abstract.The effect of temperature on growth and structure of carbon nanotubes (NTs) using chemical vapor deposition (CVD) has been investigated. Iron embedded silica was used to grow NTs in large
Growth of a Single Freestanding Multiwall Carbon Nanotube on each Nanonickel Dot
Patterned growth of freestanding carbon nanotube(s) on submicron nickel dot(s) on silicon has been achieved by plasma-enhanced-hot-filament-chemical-vapor deposition (PE-HF-CVD). A thin film nickel
High-temperature superconducting edge-type Josephson junctions with modified interface barriers
This paper describes recent results on the fabrication, electrical characteristics, and microstructure of high-temperature superconducting edge-type Josephson junctions with modified interface

These hierarchical nanomorphologies are coupled to significantly enhanced exciton dissociation, which consequently contribute to photocurrent, indicating that the nanostructural characteristics at multiple length scales is one of the key factors determining the performance of PTB7 copolymer, and likely most polymer/fullerene systems, in OPV devices.
On the origin of increased phonon scattering in nanostructured PbTe based thermoelectric materials.
It is proposed that particle-induced local elastic perturbations interfere with the phonon propagation pathway, thereby contributing to further reduction in lattice thermal conductivity, and consequently can enhance the overall thermoelectric figure of merit.
Planar GaAs nanowires on GaAs (100) substrates: self-aligned, nearly twin-defect free, and transfer-printable.
Using the concept of sacrificial layers and elevation of Au catalyst modulated by growth condition, this work demonstrates for the first time a large area direct transfer process for nanowires formed by a bottom-up approach that can maintain both the position and alignment.
