GaN Micromechanical Resonators with Meshed Metal Bottom Electrode [PDF]
Materials, 2015 This work describes a novel architecture to realize high-performance gallium nitride (GaN) bulk acoustic wave (BAW) resonators. The method is based on the growth of a thick GaN layer on a metal electrode grid. The fabrication process starts with the growth of a thin GaN buffer layer on a Si (111) substrate.

Experimental model of the interfacial instability in aluminium reduction cells [PDF]
, 2009 A solution has been found to the long-standing problem of experimental modelling of the interfacial instability in aluminium reduction cells. The idea is to replace the electrolyte overlaying molten aluminium with a mesh of thin rods supplying current ...

Thick inductive cross shaped metal meshes [PDF]
Journal of Applied Physics, 2002 Experimental data for inductive cross shaped metal meshes with periodicity constant g=20 μm have been reproduced by the Micro-Stripes simulation program for various thicknesses. A similar calculation has been performed with the Fourier modal method for cross shaped meshes with periodicity constant g=1 μm.
