Imaging ferroelectric domains

(Phys.org) —When thin films of ferroelectric materials are grown on single-crystal substrates, they can develop regions of aligned polarization—called "domains"—that often adopt complex patterns. Manipulation of ferroelectric ...

Atomic-scale catalysts may produce cheap hydrogen

Researchers at North Carolina State University have shown that a one-atom thick film of molybdenum sulfide (MoS2) may work as an effective catalyst for creating hydrogen. The work opens a new door for the production of cheap ...

'Inverse opal' structure improves thin-film solar cells

(Phys.org) —Researchers have shown how to increase the efficiency of thin-film solar cells, a technology that could bring low-cost solar energy. The approach uses 3-D "photonic crystals" to absorb more sunlight than conventional ...

Understanding what makes a thin film solar cell efficient

Swiss scientists have developed a new technique for manufacturing high-efficiency, flexible, thin film solar cells from CIGS (copper indium gallium di-selenide) semiconductors. This has enabled them to achieve an efficiency ...
