Abstract This work is to demonstrate a low cost and time-conserving technique create nano-trenches by transferring nano-scale polymeric sidewalls into substrate. The sidewall vertically spreading layer deposited spin-coating polymer solution on vertical template. By varying processing parameters such as the concentration or speed, dimension of can be changed, which, after pattern transfer, also...

The spatial profiles and the dissipation characteristics of spin-wave quasieigenmodes are investigated in small magnetic Ni81Fe19 ring structures using Brillouin light scattering microscopy. It is found, that the decay constant of a mode decreases with increasing mode frequency. Indications for a contribution of three-magnon processes to the dissipation of higher-order spin-wave quasi-eigenmode...

Electric switching of reflection resonances at near-IR spectral range is experimentally demonstrated in a reflective metamaterial twisted nematic liquid crystal cell. Reflective metamaterial composed of nano-sized double-split ring resonator aperture is fabricated by a focused ion beam milling. Two-fold rotational symmetry of double-split ring resonators allows for two orthogonal polarization-d...

A new approach of utilizing microwave to pattern gradient concentric silver nanoparticle ring structures has been presented. The width and height of a single ring and the space between adjacent rings can be adjusted by changing the silver colloidal concentration and the microwave output power. By simply enhancing the ambient vapour pressure to the saturated value during microwave-assisted evapo...

We consider a nano-system connected to measurement probes via non interacting leads. When the electrons interact inside the nano-system, the coefficient |ts(EF )| describing its effective transmission at the Fermi energy EF ceases to be local. This effect of electron-electron interactions upon |ts(EF )| is studied using a one dimensional model of spinless fermions and the Hartree-Fock approxima...
