Capacitance-Voltage Characteristics of Metal-Oxide-Strained Semiconductor Si/SiGe Heterostructures

We present theoretical investigation of mechanical strain-induced effects in metal-oxide-semiconductor (MOS) structures from an electrical point-of-view. In this work, we start by calculating the strained semiconductor band-structure using a k.p approach over the complete Brillouin [...]

Kinetic and Numerical Approaches to Nucleation and Growth During a First Order Phase Transition

ten Bosch A., Zhukhovitskii D.I., CNRS, FR

Novel nanostructures are created during first order phase transitions. Embryos of the new phase are formed by aggregation of particles which diffuse in the local field. Two model independent approaches to nucleation are described : [...]

Simulation and Characterization of High Q Microresonators Fabricated by UV – LIGA

Basrour S., Majjad H., Coudevylle J.R., Coudevylle J.R., de Labachèlerie M., CNRS, FR

This paper is devoted to a study on a new metallic microresonator realized by UV-LIGA technique. This device is excited electrostatically and takes advantage of the contour modes or Lamé-modes of the structure. Design methods [...]

Modeling a Piezoelectric Actuator Using a Transformer Equivalent Circuit

Oms-Elisabelar F., Bergaud C., Nicu L., Martinez A., CNRS, FR

In this paper, we describe both the static and dynamic behaviors of an AFM-like piezoelectric actuator using a transformer equivalent circuit in which both the electrical and mechanical portions are represented by electrical equivalencies. The [...]
