Nowadays, electrostatically driven high frequency micromechanical resonators are being developed in which the gap spacing is minimized in order to achieve sufficiently high electromechanical coupling. Typical gap spacings for resonators operated close to a GHz [...]
The atomistic physics of fluid/solid interfacial layers may substantially influence liquid flow and ion transport, particularly in nanoscale channels. Previous studies addressing non-continuum fluid mechanics have been largely based on Molecular Dynamics (MD) simulations that [...]
The key idea of the presented approach, which account for parameter variations in a single finite element run, is to compute not only the governing system matrices of the FE problem but also their partial [...]
When boundary element methods are used to solve Laplace or Helmholtz problmes associated with complicated three-dimensional geometries, the associated integral equation is typically discretized using a piecewise constant basis, and a system of equations is [...]

Nanobattary microstructure consists of anode, cathode, electrolyte, separator for miniaturized power source. Miniaturization is a challenging area of research. Miniature power sources have a variety of applications on miniature power-controlled devices. Li-Ion is selected by [...]
Quantum effects on MOS structures investigation.
The effect of the Casimir force in micro and nano electromechanical systems (MEMS/NEMS) is examined taking fully into account the dielectric properties of the materials as well as the finite thickness of movable elements in [...]
We will resented a completely generic scientific environment suitable for thearea of TCAD. Therewith it is possible for scientists to use a completetopological and numerical environment to develop applications with minimumoverhead or great knowledge of [...]
MEMS-based capacitive pressure sensors have been widely used in many engineering applications. The design of a MEMS capacitance pressure sensor presents a number of challenges, one of which is the calculation of sensor capacitance and [...]
Application of dielectrophoresis techniques to biological particles is limited by the temperature increase of the suspension due to Joule heating. This temperature increase can be obtained from a Poisson equation, but the presence of the [...]
The aim of this paper is to validate numerical simulations of electromechanical coupling in micro-structures using some experimental results. The micro-structures studied here consist in a micro-bridge and two cantilever beams. Multi-physics simulations of micro-electro-mechanical [...]
In this work, we present the optimization work for piezoelectric transformers (PT) by using the elite Genetic Algorithm (GA). The Finite-element solver, NTUPZE, is used to calculate the behaviors of piezoelectric transformers. The design parameters [...]
