Growth and Structure of Fullerene Thin Films and Other Carbon Nanomaterials

Katz E.A., Prilutskiy O., Faiman D., Shtutina S., Ezersky V., Mogilko E., Ben-Gurion University of the Negev, IL

The present paper reports relationships between structural characteristics of carbon materials and conditions of their production. C60 thin films were grown by a vacuum deposition technique on various substrates. We demonstrate effect of the substrate [...]

Stability of Charge-Controlled Electrostatic Actuators: A general theorem and a novel charge Pull-In extraction numerical scheme

Bochobza-Degani O., Elata D., Nemirovsky Y., Electrical Engineering Department, Technion, IL

This work deals with the stability of charge-controlled electrostatic actuators. First, a general proof is presented showing that for any electrostatic actuator, the stability range under charge-control is always larger than the stability range under [...]

An efficient Adaptive Single-Mode (ASM) Pull-In Extraction Algorithm for Computer Aided Design of Electrostatic MEMS Devices

Elata D., Bochobza-Degani O., Nemirovsky Y., Technion – Israel Institute of Technology, IL

This paper presents a novel Adaptive Single-Mode (ASM) Pull-In extraction scheme for CAD of electrostatic MEMS. The scheme is 50 to 1000 times faster than various previously suggested methods. The extracted Pull-In parameters are shown [...]

Modeling the Electro-Thermal Response of Thermally Isolated Micromachined Distributed Structures

Socher E., Bochobza-Degani O., Elata D., Nemirovsky Y., Israel Institute of Technology, IL

This work analyzes the electro-thermal behavior of thermally isolated micromachined resistive structures. A novel numerical scheme for solving the coupled electro-thermal problem is suggested. The novel scheme can capture the thermal instabilities under both voltage [...]
