We study the band structure of semiconductor nanowires with quantum dots embedded in them. The is calculated using Rayleigh–Ritz variational method. consider two different types, one type defined by electrostatic potentials applied to nanowire, while other adding materials offsets respect parameters nanowire. are particularly interested appearance discrete energy levels gap between conduction a...

the output of a piezoelectric nanogenerator based on zno nanowire is largely affected by the shape of nanowire. in order to obtain mechanically stable nanogenerator with high performance, the investigation of mechanical and electrical characteristics related to the nanowires and materials used in nanogenerators are of great interest and significance. this paper presents the various behavior of ...

Magnetization Dynamics in Racetrack Memory Various devices have been proposed which use magnetic domain walls (DWs) in nano-sized magnetic structures to perform logic operations or store information. In particularin ‘Racetrack memory’ bits of information represented by DWs are shifted in amagnetic wire to be stored. For these memory and logic devices to be successful, greatcontr...

For easy performance of Lorentz microscopy with simultaneous electric measurements, a special specimen holder for transmission electron microscopy (TEM) has been developed that has electromagnets to generate magnetic field and four leads for electric measurements. This TEM holder was evaluated by checking experimental results of permalloy (Ni0.8Fe0.2) patterns. Clear observations of domain wall...

The motion of magnetic nanowires can be manipulated by a magnetic field in liquids so that their distribution, alignment and orientation can be effectively controlled. The small dimensions of nanoscale entities result in an extremely low Reynolds number, and a steady state Stokes flow approximation was adopted to analyze the nanowire motion under the influences of applied field. The effects of ...

We address the problem of control of the magnetic moment in a ferromagnetic nanowire by means of a magnetic field. Based on theoretical results for the 1D Landau-Lifschitz equation, we show a robust controllability result. 1. Model and control result The magnetic moment u of a ferromagnetic material is usually modeled as a unitary vector field, solution of the Landau-Lifschitz equation (1) ∂u ∂...

The mechanical properties including elastic stiffness constants as well as bulk modulus of Palladium (Pd) nanowire were calculated in the constant temperature and pressure (NPT), ensemble by molecular dynamics (MD) simulation technique. The quantum Sutton-Chen (Q-SC) many-body potential was used to calculate the cohesive energy as well as forces experience by every atoms. The temperature and pr...
