Three-level stencil alignment fabrication of a high-k gate stack organic thin film transistor

Jürgen Brugger, Mihai Adrian Ionescu, Andreea Veronica Savu, Dimitrios Tsamados, Katrin Sidler Arnet, Nenad Cvetkovic

In this work a high-k double-gate pentacene field-effect transistor architecture is presented. The devices are fabricated on a flexible polyimide substrate by three aligned levels of stencil lithography combined with standard photolithography. ALD-deposite ...

Balancing current drive and heating in DIII-D high noninductive current fraction discharges through choice of the toroidal field

Holger Reimerdes

In order to maintain stationary values of the stored energy and the plasma current in a tokamak discharge with all of the current driven noninductively, the sum of the α-heating power and the power required to provide externally driven current must be equa ...

A Comparison Between Two-Commutation-Cell Multichannel and Multilevel Buck-Derived Topologies

Alfred Rufer, Christian Rod

In the frame of the development of a very high speed synchronous drive, a DC/DC converter is studied. In this context, this paper presents the comparison between two two-commutation-cell topologies. A multichannel and a multilevel converter are formally co ...

Inductive Power Link for a Wireless Cortical Implant With Two-Body Packaging

Catherine Dehollain, Michel Declercq, Kanber Mithat Silay

This paper presents an inductive power link for remote powering of a wireless cortical implant. The link includes a Class-E power amplifier, a gate driver, an inductive link, and an integrated rectifier. The coils of the inductive link are designed and opt ...

An Analytical Solution for the Torque and Power of a Solid-Rotor Induction Motor

Yves Perriard, Miroslav Markovic

An analytical solution for the torque and power of a solid-rotor two-pole three-phase slotless induction motor is presented. The field excitation is a current layer placed at the stator interior surface. The solution is based on an analytical solution of t ...

Railway Catenary Parameters Identification based on Harmonic Current Injection

Alfred Rufer, Behrooz Bahrani, Martin Aeberhard

Modern trains with active line-side converters are currently the state-of-the-art technology in the traction industry. In such systems, the active line-side converter of the drive system can be exploited for power quality improvement purposes. In this pape ...

Vibration and shock reliability of MEMS: modeling and experimental validation

Herbert Shea, Robert Andrew Lockhart, Subramanian Sundaram, Maurizio Tormen

A methodology to predict shock and vibration levels that could lead to the failure of MEMS devices is reported as a function of vibration frequency and shock pulse duration. A combined experimental–analytical approach is developed, maintaining the simplici ...

Electron-hole bilayer tunnel FET for steep subthreshold swing and improved ON current

Mihai Adrian Ionescu, Luca De Michielis, Livio Lattanzio

We propose a novel Tunnel field-effect transistor (TFET) concept called the electron-hole bilayer TFET (EHBTFET). This device exploits the carrier tunneling through a bias-induced electron-hole bilayer in order to achieve improved switching and higher driv ...

Unconstrained three-dimensional reaching in Rhesus monkeys

Grégoire Courtine

To better understand normative behavior for quantitative evaluation of motor recovery after injury, we studied arm movements by non-injured Rhesus monkeys during a food-retrieval task. While seated, monkeys reached, grasped, and retrieved food items. We re ...
