Instability of Flatband Voltage in HfO2 Gate Stack Structures under Reducing/Oxidizing Annealing Conditions

We have applied a combinatorial approach to fabricate work function (WF) tuned Pt-W alloy films and used the films as metal electrodes for HfO2/SiO2/Si capacitors. As the ratio RPt of Pt to W changes from 0 to 1, the WF value varies continuously from 4.7

Surface Grafting of Polypyrrole onto Silicon Wafers

A micromolding technique in capillaries was adapted to make uniform patterns of polypyrrole (Ppy), and the conductivities of the patterns were measured by direct contact IV curves and conductance AFM methods. Noncovalently bound Ppy patterns have high

Texture and Phase Analysis of a Ca 3 Co 4 O 9 / Si (100) Thermoelectric Film

July 26, 2007

Winnie K. Wong-Ng, Y F. Hu, Mark D. Vaudin, B He, Makoto Otani, Nathan Lowhorn, Q Li
This paper reports the texture analysis as well as the identification of two crystalline phases between a thin film of monoclinic Ca3Co4O9 and a cubic (100) Si substrate, using a diffractometer equipped with a 2-dimensional area detector. No reflections

Model, Prediction and Experimental Verification of Composition and Thickness in Continuous Spread Thin Film Combinatorial Libraries Grown by Pulsed Laser Deposition

July 16, 2007
Author(s)
Nabil Bassim, Peter K. Schenck, Makoto Otani, Hiroyuki Oguchi
Pulsed laser deposition (PLD) is a powerful technique for growing continuous spread thin film libraries of continuously varying composition as a function of position on a substrate. Continuous spread thin film libraries are grown by striking a ceramic

Microfluidic Dynamic Light Scattering Used for High Throughput Measurements

July 10, 2007
Author(s)
Thomas Q. Chastek, Kathryn L. Beers, Eric J. Amis
When diluted in some solvents, surfactants and block copolymers self-assemble into micelles or vesicles of about 10-100 nm in size. There is a great deal of interest in micelles and vesicles because they are widely used in the formulations industry, and

Domain Ordering of Strained 5ML SrTiO 3 Films on Si(001)

June 26, 2007
Author(s)
P Ryan, Joseph Woicik, D Wermeille, J.-W Kim, C S. Hellberg, H Li
We present high resolution X-ray diffraction data indicating regularly ordered square shaped coherent domains approximately 1200A in length co-existing with longer approximately 9500A correlated regions in a highly strained 5ML SrTiO3 (STO) film grown on

Margin Failures in Crown-Like Brittle Structures: Off-Axis Loading

June 11, 2007
Author(s)
Chris Ford, T Qasim, M T. Bush, X Z. Hu, Mahek Shah, Vibhu Saxena, Brian R. Lawn
The effect of off-axis loading of compliant indenters on the initiation of cracks at the margins of dental crown-like dome structures consisting of glass shells back-filled with an epoxy resin is examined. As in previous studies on similar structures but
