Program Highlights

Molecular Nano-Ring Beats Like a Chime

Perfect rings of C60 molecules, lined up around circular layers of silver, reveal an important property of nanoelectronic contacts: thermal energy causes

Novel multiferroic thin film memory devices

Electric-field tunable spin valves are being investigated

Discovery of a Pb-free morphotropic phase boundary (MPB) in a high Tc piezoelectric perovskite

Piezoeletric materials are used for a variety of actuator and sensor applications. Finding a Pb-free replacement for the popular Pb(Zr,Ti)O3 has been a major challenge for the community.

High-performance Transparent Inorganic-organic Hybrid Thin-film n-type Transistors

Thin-film transistors, already indispensable in a number of portable electronics, would benefit from optical transparency and compatibility with flexible, lightweight plastics.

Structural and Morphological Control of Multifunctional Oxide Nanostructures at Multi-dimensions

Oxide ceramics are ubiquitous in modern society- ranging from capacitors in electronic gadgets to high-tech displays. In numerous future technologies, it is necessary to "pattern" ceramic oxides in various forms, e.g., dots and lines, at the nanometer scale.

Bringing Technology to the Classroom

The recent MRSEC Teacher Workshop at UCSB was a Great Success. Junior High and High School math and science teachers from Santa Barbara, Ventura and Los Angeles Counties visited the UCSB Materials Research Laboratory for a day of curriculum presentations and workshops.

Solid State Lighting: Energy Savings and New Architecture

To a packed audience of over 200 students and local residents, the UCSB MRL supported a public lecture on the subject of solid state lighting, emphasizing the promise of a much cleaner, more efficient, and longer-lasting lighting source. Santa Barbara architect

A New and Safe 'X-Ray' Vision

UCSB MRL researchers have recently developed a new way of seeing beneath clothing and other materials using a THz imaging system that employs a photoconductive switch for illumination and a zero-biased, Schottky diode for detection.

Graphitic Carbon Produced at Very Low Temperatures During the Synthesis of Iron Oxide Nanoparticles

Graphitic carbon - structural forms of the element that are constructed exclusively from carbon atoms having trigonal planar coordination - is ordinarily produced under drastic physical and conditions, typically at temperatures in excess of 500° C. Columbia MRSEC scientists have uncovered a process by which this form of matter can assemble at temperatures as low as 110° C.
