single-crystalline silicon micromirrors
We have developed a novel wafer-scale single-crystalline silicon micromirror bonding process to fabricate optically flat micromirrors on polysilicon surface-micromachined 2D scanners. The electrostatically actuated 2D scanner has a mirror area of 450 jtm x 450 tm and an optical scan angle of Compared to micromirrors made with a standard polysilicon surface-micromachining process, the radius of ...
متن کاملCrack front dynamics across a single heterogeneity.
We study the spatiotemporal dynamics of a crack front propagating at the interface between a rigid substrate and an elastomer. We first characterize the kinematics of the front when the substrate is homogeneous and find that the equation of motion is intrinsically nonlinear. We then pattern the substrate with a single defect. Steady profiles of the front are well described by a standard linear ...
متن کاملSingle crystalline mesoporous silicon nanowires.
Herein we demonstrate a novel electroless etching synthesis of monolithic, single-crystalline, mesoporous silicon nanowire arrays with a high surface area and luminescent properties consistent with conventional porous silicon materials. These porous nanowires also retain the crystallographic orientation of the wafer from which they are etched. Electron microscopy and diffraction confirm their s...
متن کاملFabrication of Single-Crystalline Silicon Nanowires by Scratching a Silicon Surface with Catalytic Metal Particles
The successful synthesis of carbon nanotubes has stimulated much research in nanomaterials, in particular, in semiconducting nanostructures, which are interesting for their novel sizeand dimensionality-dependent physical properties, and their potential applications in nanoscale optoelectronics. Silicon is the most important semiconducting material, with its contemporary microelectronic technolo...
متن کاملReaction Front Evolution during Electrochemical Lithiation of Crystalline Silicon Nanopillars
Silicon is one of the most promising anode materials for use in rechargeable lithium-ion batteries due to its high theoretical specific capacity of 4200 mAhg 1 and low cost. However, this high lithium storage capacity results in enormous volume expansion and contraction during electrochemical lithiation and delithiation, which can induce mechanical fracture and severe capacity fading. Recently,...
