Oxygen Vacancies induced ferromagnetism in undoped and Cr doped SnO2 nanowires

Zhang L., Ge S., Zuo Y., Jing Q., Lanzhou University, CN

Observations of room temperature ferromagnetism (FM) in various pristine oxides have been reported recently. The findings have urged researchers to explore the origin of FM, but there is no uniform model to explain this issue [...]

Large-Deflection Beam Model for Schematic-Based Behavioral Simulation in NODAS

Jing Q., Mukherjee T., Fedder G.K., Carnegie Mellon University, US

MEMS design in NODAS is based on a geometrically intuitive schematic representation of MEMS using a small set of atomic elements (anchors, beams, plates and electrostatic gaps), each of which is associated with a geometrically [...]

Convergence and Speed Issues in Analog HDL Model Formulation for MEMS

Iyer S., Jing Q., Fedder G.K., Mukherjee T., ECE Department, Carnegie Mellon University, US

Behavioral simulation using high-level hardware description languages (HDLs) is becoming increasingly relevant for mixed-domain MEMS simulation. In this paper three issues which impact the convergence and simulation time in MEMS behavioral simulations are addressed. First, [...]

Simulation and Characterization of a CMOS Z-axis Microactuator with Electrostatic Comb Drives

Xie H., Erdman L., Jing Q., Fedder G.K., Carnegie Mellon University, US

This paper reports the first design and its simulation and experimental results of a CMOS z-axis microactuator that utilizes the vertical electrostatic forces existing between multi-conductor comb fingers. The measured maximum displacement of the z-axis [...]
