In this paper, we have demonstrated a viable microstrip array patch antenna technology for the first time on GaN-on-low resistivity silicon (LR-Si) substrates (ρ < 40 Ω.cm) at H-band frequencies (220–325 GHz). The developed technology is compatible with standard MMIC technology with no requirement for high temperature processes. To mitigate the losses presented by the substrate and to enhance the...
We demonstrate a simple and cost-effective method for fabricating silver-nanoparticle metamaterial structures on a flexible substrate based on inkjet printing. Specifically, we used inkjet printing with an ordinary printer to obtain an array of split-ring resonators (SRRs) on a sheet of paper. We designed the SRR array to exhibit a resonance in the THz region, which we observed through THz time-domain...
Intensive research is currently being aimed at understanding both the growth and the physical properties of a wide range of two-dimensional (2D) materials [1], since this class of materials is expected to lead to entirely new types of devices on the nanoscale. Additionally, the introduction of magnetic dopants into a 2D lattice can bring out new functionalities, providing new opportunities for spintronic...
In order to achieve aggressive scaling of the equivalent oxide thickness (EOT) and simultaneously reduce leakage currents in logic devices, silicon-based oxides (SiON / SiO2) have been replaced by physically thicker high-κ transition metal oxide thin films by many manufacturers starting from the 45 nm technology node. CMOS process compatibility, integration and reliability are the key issues to address...
