Magnetometry Measurements of Nanomagnetic Materials

Dodrill B.C., Lake Shore Cryotronics, US

Magnetometers are used to characterize magnetic material properties. Magnetometry techniques can be broadly classified into two categories: inductive and force-based. The two most commonly used inductive techniques are vibrating sample (VSM) and superconducting quantum interference [...]

Fabrication and modeling of resistance switching cells for ReRAM applications

Pawlikiewicz M., Kalkur T.S., University of Colorado Colorado Springs, US

This paper presents the technology, fabrication process, measurements and SPICE-compatible modeling of resistance switching devices. Those devices were built using nickel oxide (NiO) as for oxide layers between two platinum layers that were used as [...]

Trap-induced apparent linearity of CNTFETs (invited)

Haferlach M., Claus M., TU Dresden, DE

Compared to conventional bulk semiconductors carbon nanotubes (CNTs) possess a number of properties which may make CNT technology superior for certain applications. In particular, the one-dimensional (1D) transport in CNTs leads not only to a [...]

Understanding and Modeling Quasi-Static Capacitance-Voltage Characteristics of Organic Thin-Film Transistors

Ucurum C., Goebel H., Helmut Schmidt University - University of the Federal Armed Forces Hamburg, DE

We have investigated the quasi-static capacitance-voltage (C-V) characteristics of pentacene-based organic thin-film transistors (OTFTs). Beside the hysteresis which is in accordance with previously reported I-V characteristics of OTFTs, the measured C-V characteristics include a plateau [...]

Hysteresis-free spin valves for GMR sensors

Ustinov V.V., Milyaev M.A., Naumova L.I., Proglyado V.V., Krinitsina T.P., Institute of Metal Physics, RU

Top spin valves Ta/[FeNi/CoFe]/Cu/ CoFe/AFM/Ta based on antiferromagnetics (AFM) Fe50Mn50 and Mn75Ir25 with varying [Fe20Ni80/Co90Fe10] composite free layer parameters and Cu interlayer thickness were prepared by DC magnetron sputtering. GMR characteristics of spin valves (SV) [...]

Dynamic change in water meniscus arising from tapping of an AFM tip

Hong S.D., Choi H.J., Ha M.Y., Jang J., Pusan National University, KR

We perform a molecular dynamics simulation to emulate the retraction followed by re-approach of an AFM with respect to a surface. We found a hysteresis in the snap-off distance and energy during such a tapping [...]

Impact of Gate Induced Drain Leakage and Impact Ionization Currents on Hysteresis Modeling of PD SOI Circuits

Chen Q., Suryagandh S., Goo J-S, An J.X., Thuruthiyil C., Icel A.B., Advanced Micro Devices, US

The impact of the gate induced drain leakage and impact ionization currents on hysteresis of PD FB SOI circuits is examined, and a physical understanding is provided. Measured silicon data from 90nm and 65nm PD [...]

Modeling hysteresis and creep characteristics of a carbon-nanotube-reinforced electroactive actuator

Sohn K., Shin S.R., Yi B-J, Kim S.I., Kim S.J., Kim S.I., Kim S.J., Hanyang University, KR

For smart materials that are useful in wide variety of applications such as microelectromechanical systems (MEMS), machine components, and artificial muscle, the nonlinear phenomena of hysteresis and creep are essential consideration. We investigated movement of [...]

An A Priori Hysteresis Modeling Methodology for Improved Efficiency and Model Accuracy in Advanced PD SOI Technologies

Chen Q., Goo J-S, Subba N., Cai X., An J.X., Ly T., Wu Z-Y, Suryagandh S., Thuruthiyil C., Radwin M., Zamudio L., Yonemura J., Assad F., Pelella M.M., Icel A.B., Advanced Micro Devices, US

Exploiting the asymmetric nature of interactions among hysteresis, “nonFET”, and DC characteristics, an a priori hysteresis modeling methodology has been proposed as an essential part of an improved model extraction flow for advanced PD SOI [...]

Modeling and Analysis of Hysteresis Phenomena in Electrostatic Zipper Actuators

Guidotti P., Bernstein D., California Institute of Technology, US

We investigate the relationship between the pull-in phenomenon for electrostatic actuators and the hysteresis effect found in zipper actuators. Liked lumped mass and spring and tension based membrane models, we show that a beam model [...]
