Semimetals are high conductors

Researchers in China and at UC Davis have measured high conductivity in very thin layers of niobium arsenide, a type of material called a Weyl semimetal. The material has about three times the conductivity of copper at room ...

Researcher identifies defects in solar cells made of silicon

Since he was a teenager, engineer Sergio Castellanos had the desire to study abroad to prepare and do research in the best laboratories, particularly on solar energy. With six years of study in the United States, first at ...

All that glitters is not gold

(PhysOrg.com) -- Researchers developing key new technology electronics like quantum computing or advanced detectors, as well as those studying basic material science and metal surface properties, often find their experiments ...

Small defects mean big problems for industrial solar cells

Nanoscale clustering of metal impurities at intragranular dislocations within industrial mc-Si solar cells have been observed by users from the Massachusetts Institute of Technology working with the Center for Nanoscale Materials ...
