This paper is concerned with the development of new simple 4-noded locking-alleviated smart finite elements for modeling the smart composite beams. The exact solutions for the static responses of the overall smart composite beams are also derived for authenticating the new smart finite elements. The overall smart composite beam is composed of a laminated substrate conventional composite beam, a...

Spectroscopic ellipsometry and high resolution transmission electron microscopy have been used to characterize microcrystalline silicon films. We obtain an excellent agreement between the multilayer model used in the analysis of the optical data and the microscopy measurements. Moreover, thanks to the high resolution achieved in the microscopy measurements and to the improved optical models, tw...

We demonstrate for the first time the successful layer transfer of an epitaxially grown monocrystalline Si film from a purely chemically etched porous Si substrate of 150 mm diameter to a glass carrier. The surface conditioning for all Si layer transfer processes based on porous Si has been, up to now without exception, carried out by electrochemical etching. In contrast, our chemical stain etc...

in this paper metal-assisted chemical etching has been applied to pattern porous silicon regions and silicon nanohole arrays in submicron period simply by using positive photoresist as a mask layer. in order to define silicon nanostructures, metal-assisted chemical etching (mace) was carried out with silver catalyst. provided solution (or materiel) in combination with laser interference lithogr...

Crystalline calcium carbonate was deposited on various substrates (substrate temperature of 80 °C) from a saturated hydrogen solution (solution 10 °C). A single aragonite phase the Al substrate, whereas mixed and calcite grew soda lime glass, borosilicate silica polycarbonate substrates. With increasing deposition time, crystal size proportion silicate glass substrate increased. Furthermore, cr...

Vertical cavity surface emitting laser (VCSEL) is attractive light source in a future massively parallel computing system with many processor elements (PEs). We proposed optical interconnection by wavelength domain addressing for realizing switch-less and reconfigurable interconnection [1]. For such a system, 1.3 µm VCSEL has advantages over short wavelength VCSEL such as 0.98 µm VCSEL because ...

We consider the interaction between nematic liquid crystals (NLCs) and polymer substrates. Such substrates can interact with NLCs, exhibiting a phenomenon known as director gliding: the preferred orientation of the NLC molecules at the interface changes on time scales that are slow relative to the elastic relaxation time scale of the NLC. We present two models for gliding, inspired by experimen...

A multi-layer nanogap array composed of three linearly aligned gold nanogaps is fabricated for a surface-enhanced Raman spectroscopy (SERS) substrate. The overall process for the proposed structure is simple and reliable with the use of a photolithography-free fabrication process, which includes only deposition and etching. Chemical vapor deposition (CVD) is employed to form a uniform and highl...

In this work, we demonstrate a single-layer encapsulation method for poly(3,4ethylenedioxythiophene) (PEDOT). This method is achieved by initiated chemical vapor deposition (iCVD) process, which is scalable and employs solvent-free and low-substrate temperature conditions. The encapsulant used, poly(divinylbenzene-co-maleic anhydride) (PDVB-MA), was first time synthesized via vapor phase proces...
