In two-probe impedance measurements the interfacial impedance between metal electrode and ionic conductor contributes to the measured impedance. Therefore a calculation procedure which separates the bulk from the interfacial impedance must be applied. The separation procedure can be avoided by measuring the bulk conductivity in the four-probe arrangement. The impedance of polycrystalline sample...

The overall aim of this study is to calculate some water properties in the single wall carbon naotubes (SWCNT) and compare them to the bulk water properties to investigate the deviation of water properties inside the SWCNT from those in the bulk. Here some physical and transport properties of water molecules in the single wall carbon nanotube were reported by performing molecular dynamics (MD) ...

Transparent conductors are essential in many optoelectronic devices, such as displays, smart windows, light-emitting diodes and solar cells. Here we demonstrate a transparent conductor with optical loss of ∼1.6%, that is, even lower than that of single-layer graphene (2.3%), and transmission higher than 98% over the visible wavelength range. This was possible by an optimized antireflection desi...

In this paper, we reformulate the quasi-static spectral domain analysis (SDA) applicable to a lossy anisotropic multilayer asymmetric coplanar waveguide (ACPW). The SDA formulation also incorporates two-layer model of a conductor thickness and the concept of effective permeability to account for the low frequency dispersion due to the magnetic field penetration in an imperfect conductor. The pa...

The present paper describes novel microfabrication techniques which utilize an ion migration at the microcontact between ion conductor and target solid. Two different methods have been recently proposed by our group. One is a solid state electrochemical route for pinpoint doping using an ion conductor. In this approach, an electric field is applied to the solid­solid interface between the catio...
