We report the unexpectedly excellent dielectric properties of amorphous thin films with compositions in the Bi–Ti–O system. Films were deposited by RF magnetron reactive co-sputtering. In the composition range of 0.5 < x < 0.7, amorphous Bi1−xT

We have systematically studied the composition dependence of the dielectric properties of Zr1-xAlxO2-x/2 and Zr1-xSixO2. An essentially linear variation of the static dielectric constant, εs, was observed as a function of composition, x, for composi

This paper presents a novel one-transistor low-voltage DRAM-Flash hybrid memory. The proposed device integrates ferroelectric thin film and nonvolatile charge injection, and demonstrates two modes of operations: 1) a fast (10-100 ns) DRAM mode with ~

Low-frequency noise, i.e., 1/f noise severely limits the low-frequency performance of magnetoresistive sensors for applications as ultrasensitive magnetic sensors. The combination of a flux concentrator and chopping system has been proposed to mitiga

We have investigated the structural and dielectric properties of two complementary amorphous oxide systems, Ta-Ge-O and Ta-Si-O. We found that these two chemically similar amorphous systems exhibit substantially different composition-property trends.

We report the use of a small concentration of ethanol in addition to ethylene as the carbon source for growth of dense vertically aligned “forests” of few-walled carbon nanotubes (CNTs). Through a detailed comparison of CNTs grown with and withou

The ability to calculate composition in composition spread thin films is a powerful tool in combinatorial research. This ability is pivotal in high-throughput studies, where the time and effort required to determine elemental compositions using stand

We used a high-throughput method to screen for direct methanol fuel cell anode electrocatalysts in the Pt–Bi–Pb system. Previous studies showed that PtBi and PtPb (both NiAs structure type) were active electrocatalysts for the oxidation of formic

A novel method of achieving a negative index of refraction in the far-infrared region using intrinsic material properties is proposed. SrTiO3 has a dielectric resonance at ~100?cm?1 that can be lowered by lowering the temperature or with Ba doping. N

High quality epitaxial (SrTiO3∕NiO)n∕MgO thin film multiferroic heterostructures have been fabricated using reactive off-axis sputtering. Crystal quality is verified using x-ray diffraction and ion channeling. These heterostructures comprise of d
