Rutgers Physicists Find Unusual Electronic Properties in Bismuth-based Crystalline Material
February 19, 2009
Rutgers physicists have discovered unusual electronic properties in a material that has the potential to improve solar cell efficiency and computer chip design. They determined that a crystal made of bismuth, iron and oxygen can act as a reversible diode, and that diodes made from this material generate current when light falls on them. The material appears sensitive to light at the blue end of the spectrum, a property that could increase solar cell efficiency.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2016, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
