Chemical Vapor Deposition (CVD) finds application in many manufacturing processes of microelectronic devices and MEMS as a recent development. It is also useful for preparation of functionalized surfaces in microsensor kind of devices. The phenomena that is studied is deposition of a crystalline material for example Silicon from the gas phase substance such as Silicon Hydride (SiH4). The ...

Introduction: Existing solar cell (photovoltaic, PV) device simulation software is either open source with limited capabilities (1D only) [1,2] or extremely expensive with obscure functionality . PV researchers need an accessible and versatile simulation tool to optimize existing technologies and to reduce the time from concept to prototype for new technologies. This work demonstrates how ...

The use of grating couplers to couple conventionally phased and polarized light near vertically in and out of optical slab or film waveguides  represents an attractive method to interface optical fiber to photonic ICs. Previously developed grating coupler designs use transversely uniform grating structures matched to conventional scalar fiber modes. The performance of these geometries can be ...

Deep Brain Stimulation (DBS) is a therapeutic tool used for a number of neurological disorders including chronic pain, incontinence and movement disorders, such as Parkinson’s disease. DBS consists of the low-frequency stimulation of an area of the brain, known as basal ganglia. The stimulation is provided by clinical implant, consisting of a pulse generator and an electrode lead ...

We use finite elements simulations in order to study the fluid flow behavior in a chamber of a preconcentrator. We realized that most part of the fluid does not affect our preconcentrator because it is going out the chamber at high distance above it and parallel to the preconcentrator. So, we are wasting most part of our fluid and we need a lot of time to have a good concentrator factor. We ...

This paper describes the modeling of an electrochemical biosensor embedded in a microfluidic channel to determine the concentration of a target biomolecule. The total amount of analyte in the sample can be calculated by integrating the analyte concentration over the duration of the peak current. The biosensor is constructed by immobilizing redox-enzyme on an interdigitated array (IDA) electrode ...

A very simplified system for high voltage test is studied, considering reason for voltage holding failures which are not covered by conventional and local design criteria. A first understanding of the problem is obtained by solving the electrostatic potential in a 2D axis symmetric geometry, considering in detail the electrode shapes, and following a cascade of particle between opposite ...

Chaotic systems may lead to instability, extreme sensitivity and performance reduction. Therefore it is unwanted in many cases. Due to these undesirable characteristics of chaos in practical systems, it is important to recognize such a chaotic behavior. The existence of chaos has been discovered in several areas during the last 30 years. However, there is a lack of studies in relation with ...

The objective of this paper is to study the effects of compliance mismatch in a stented artery. COMSOL Multiphysics is used to tackle this challenging problem involving fluid-structure interaction. The particular effects studied in this paper are the radial displacement of the artery wall, pressure distribution along the studied segment, the factors affecting stress in the fluid and artery ...

New geothermal energy sources hold promise for the future. Deep submarine geothermal energy related to hydrothermal vents is emerging in many places along the oceanic spreading centers. Shallow submarine geothermal systems are found near to continental platforms. We present the initial development of mathematical models to simulate the energy transport in submarine systems. A model for the ...
