Exciton, exciton on the wall

Researchers have observed, in metals for the first time, transient excitons – the primary response of free electrons to light. Here, the researchers discovered that the surface electrons of silver crystals can maintain the excitonic state more than 100 times longer than for the bulk metal, enabling the excitons to be experimentally visualized by a...

Pinholes be gone

Researchers at the Okinawa Institute of Science and Technology Graduate University (OIST) have eliminated problematic pinholes in the top layer of next-generation solar cells in development. At the same time, they have significantly improved the lifetime of the solar cell and made it thinner. The findings were recently published in ("Substantial improvement...

Researchers demonstrate full-color organic light-emitting diodes with photoresist technology for organic semiconductors

FUJIFILM Corporation and nano-electronics research institute, imec, have demonstrated full-color organic light-emitting diodes (OLED)*1 by using their jointly-developed photoresist technology*2 for organic semiconductors, a technology that enables submicron*3 patterning. This breakthrough result paves the way to producing high-resolution and large...
