3D printing has emerged as an attractive way of formulating structured adsorbents, it imparts lower manufacturing costs compared to hydraulic extrusion while also allowing for unprecedented geometric control. However, binderless structures have not been fabricated by printing, ink formulation previously required clay binders which cannot be easily removed. In this study, we report the developme...

This paper presents the different processing steps of a new generic surface micromachining module for MEMS hermetic packaging at temperatures around 180°C based on nickel plating and photoresist sacrificial layers. The advantages of thin film caps are the reduced thickness and area consumption and the promise of being a lowcost batch process. Moreover, sealing happens by a reflow technique, giv...

The authors present a simplified fabrication method for the creation of free-standing dielectric mirrors for use in monolithic wavelength tunable surface-normal photonic devices, including vertical-cavity surface emitting lasers. This process utilizes a nonplasma dry etching process, based on the noble gas halide, xenon difluoride XeF2 , to remove an inorganic sacrificial film comprised of low-...

Shape Deposition Manufacturing (SDM) is a layered manufacturing process capable of building complex 3D parts through the combination of material addition and subtraction. Overhangs can be built with the help of sacrificial support materials. SDM achieves high surface quality by taking advantage of material subtraction by CNC machining. High surface quality in turn enables the fabrication of pre...

In this work, we present a method able to fabricate thin GaN nanomembranes fit for device applications. Starting from commercial GaN on sapphire substrates, MBE was used to deposit a sacrificial layer, which comprises of a superlattice of InN/InGaN, after which thin a GaN film of hundreds of nanometers thickness was grown on top. Pulsed laser irridiation with photon energy of 2.3eV gives rise t...
