Electric-field tunable spin valves are being investigated
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.
Thin-film transistors, already indispensable in a number of portable electronics, would benefit from optical transparency and compatibility with flexible, lightweight plastics.
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.
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.
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
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 - 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.
