Effects of Pt Sacrificial Layer on Microfabrication in Layered Bismuth-based Ferroelectric Thin Films

Probing intrinsic polarization properties in bismuth-layered ferroelectric films

Tunable Schottky Barrier in Photovoltaic BiFeO3 Based Ferroelectric Composite Thin Films

We examine the photo-assisted polarization loop in a BiFeO3 thin film under UV light illumination. BiFeO3 thin film prepared by pulsed laser deposition method onto the BaTiO3 thin film and the polarization behavior has been measured under poling voltage. Our results show the engineered polarization due to controllable schottky barrier under inverse poling voltage. This control on schottky barri...

Simulation of Ferroelectric Thin Films

The hysteresis properties of ferroelectric thin films open an elegant and promising way to build nonvolatile memory cells. Our basic goal is to set up a tool which is able to reproduce the macroscopic behavior of the devices by calculating current, voltage and charge at the contacts correctly. Our tool, MINIMOS-NT, provides a rigorous approach to describe the static hysteresis properties of fer...

Cucurbit[8]uril-based stimuli-responsive films as a sacrificial layer for preparation of free-standing thin films.

A pseudo-polycation was prepared based on the supramolecular cucurbit[8]uril ternary complex. It was then layer-by-layer assembled with poly(acrylic acid) to fabricate a stimuli-responsive film, which exhibited disassembly properties in response to stimuli, providing a supramolecular route for the fabrication of free-standing thin films.

Photodefinable PDMS thin films for microfabrication applications

In this work, direct patterning of polydimethylsiloxane (PDMS) is demonstrated by the addition of a UV-sensitive photoinitiator benzophenone. As an improvement to our previous work, patterns with both positive and negative features have been fabricated on the same substrate. Infrared spectroscopy was used to investigate photocrosslinking behavior and reaction chemistry of this new photodefinabl...
