Various fluxing materials are added to technical ceramics in an attempt to lower their sintering temperatures and make their processing economical. The effect of 0·3 wt% Li2CO3 addition on the phase, microstructure, phase transition temperatures and dielectric properties of BaTiO3 was investigated in the present study. The addition of 0·3 wt% Li2CO3 was observed to lower the optimum sintering t...

The scaling of silicon-based MOSFET technology beyond the 22 nm node is challenging. Further progress requires new materials, innovative structures, and even novel device concepts. All the emergent channel materials need perfect top-gate dielectric stacks in order to sustain their potential device performance. ALD high-k as a common gate stack solution finds itself very successfully integrated ...

We analyze a modern-day 65nm MOSFET technology to determine its electrical characteristics and intrinsic ballistic efficiency. Using that information, we then predict the performance of similar devices comprised of different materials, such as high-k gate dielectrics and III-V channel materials. The effects of series resistance are considered. Comparisons are made between the performance of the...

Near-field microwave microscopy has created the opportunity for a new class of electrodynamics experiments of materials. Freed from the constraints of traditional microwave optics, experiments can be carried out at high spatial resolution over a broad frequency range. In addition, the measurements can be done quantitatively so that images of microwave materials properties can be created. We rev...

Electromagnetic materials with tunable permeability and permittivity are highly desirable for wireless communication and radar technology. However, the tunability of electromagnetic parameters is an immense challenge for conventional materials and metamaterials. Here, we demonstrate a magnetically tunable Mie resonance-based dielectric metamaterials. The magnetically tunable property is derived...

We continue the development of a manifestly four-dimensional, completely covariant, approach to transformation optics in linear dielectric materials begun in a previous paper. This approach, which generalizes the Plebanski based approach, is systematically applicable for all transformations and all general linear materials. Importantly, it enables useful applications such as arbitrary relative ...

Microwave nondestructive testing methods become nowadays ever more exploited electromagnetic evaluation method not only dielectric but also metal materials surface and volume homogeneity. A novel microwave sensor created from open waveguide with metamaterial structure for non-destructive testing was developed in an attempt to increase the sensitivity of the microwave nondestructive evaluation m...

Introduction Colloidal self-assembly has been widely explored as a route to photonic materials. Theoretical work has demonstrated that a three dimensional photonic band gap can be generated from an inverse FCC structure if fairly rigorous dielectric contrast conditions are met. It is because of this finding that a multitude of research groups are investigating the self-assembly of colloidal par...
