Converse mode piezoelectric coefficient for lead zirconate titanate thin film with interdigitated electrode

Paul Muralt, Ramin Matloub Aghdam, Robin Nigon, Silviu Cosmin Sandu, Andrea Mazzalai, Nachiappan Chidambaram, Davide Balma

The use of interdigitated electrodes (IDEs) in conjunction with ferroelectric thin films shows many attractive features for piezoelectric MEMS applications. In this work, growth of {1 0 0}-textured lead zirconate titanate (PZT) thin films was achieved on i ...

Polarization Switching and Domain Wall Motion in Circular and Ring Capacitor Structures in PZT Thin Films

Nava Setter, Ludwig Feigl

Ferroelectric switching in circular and ring capacitors has been performed using a stroboscopic mode of piezoresponse force microscopy. A simple geometric model incorporating the characteristic domain wall motion is sufficient to describe the switching of ...

A Modeling Environment for the Simulation and Design of Charge Redistribution DACs Used in SAR ADCs

Andrea Bonetti

The optimal design of successive approximation register (SAR) analog-to-digital converters (ADCs) requires the accurate estimate of nonlinearity and parasitic capacitance effects in the feedback charge-redistribution digital-to-analog converters (DACs). Si ...

A Simulation and Modeling Environment for the Analysis and Design of Charge Redistribution DACs used in SAR ADCs

Andrea Bonetti

The optimal design of SAR ADCs requires the accurate estimate of nonlinearity and parasitic effects in the feedback charge-redistribution DAC. Since the effects of both mismatch and stray capacitances depend on the specific array topology, complex calculat ...

Digitization Technique for UWB Receiver and Capacitive Sensor Interface

Shenjie Wang

As CMOS processes continue to scale to smaller dimensions, the increased fT of the devices and smaller parasitic capacitance allow formore power efficient and faster digital circuits to be made. But at the same time, output impedance of transistors has gon ...

Large Arrays Of Inkjet-Printed Mems Microbridges On Foil

Nico de Rooij, Danick Briand, Francisco Molina Lopez

This works describes the fabrication process of an array of printed MEMS microbridges on polymeric foil, performed in only four easy steps. Each functional material was deposited exclusively by inkjet-printing technique, compatible with large-area fabricat ...

Ab initio self-consistent total-energy calculations within the EXX/RPA formalism

Nicola Colonna, Ngoc Linh Nguyen

Calculations of exact-exchange (EXX) and random phase approximation (RPA)-correlation energies within the formally exact adiabatic connection fluctuation-dissipation theorem formalism have recently been carried out for a number of isolated and condensed sy ...

Defect states characterization of non-annealed and annealed ZrO2/InAlN/GaN structures by capacitance measurements

Nicolas Grandjean, Jean-François Carlin

InAlN/GaN metal-oxide-semiconductor structures with non-annealed and annealed ZrO2 gate insulators were characterized by capacitance-voltage (C-V) measurements. A significant capacitance hysteresis in both channel depletion and barrier accumulation regions ...

Single-walled carbon nanotubes functionalized with polydiphenylamine as active materials for applications in the supercapacitors field

Arnaud Magrez

Composites based on polydiphenylamine (PDPA) doped with heteropolyanions of H3PW12O40 and single-walled carbon nanotubes (SWNTs) were prepared by electrochemical polymerization of diphenylamine (DPA) on carbon nanotube films deposited onto Pt electrodes. H ...

A transmission line model for plasmon propagation on a graphene strip

Julien Perruisseau-Carrier, Juan Sebastian Gomez Diaz

We present a transmission line model for TM plasmon propagation along a graphene strip, and derive closed-form expressions for the kinetic and Faraday inductance, resistance, and electrostatic capacitance of the equivalent circuit as a function of graphene ...
