Rice lab uses CMOS-compatible aluminum for on-chip color
detection
Rice University researchers have created a CMOS-compatible,
biomimetic color photodetector that directly responds to red, green and blue
light in much the same way the human eye does.
The new device was created by researchers at Rice’s
Laboratory for Nanophotonics (LANP) and is described online in a new study in
the journal Advanced Materials. It uses an aluminum grating that can be added
to silicon photodetectors with the silicon microchip industry’s mainstay
technology, “complementary metal-oxide semiconductor,” or CMOS.
