Accident Could Lead To Better Digital Cameras
Dave Bullock (eecue) writes "Scientists at UCLA have accidentally created a material that will some day give us better, faster, cheaper, more flexible digital cameras. I toured their lab and shot a photo essay for Wired. Personally I'm looking forward to a quantum-dot embedded camera sensor someday soon. 'Graduate student Hsiang-Yu Chen was working on a new formula for solar cells when something went wrong. Instead of creating electricity when hit with light, the conductivity of the material she was working with changed. "The original purpose [was] to make a solar cell more efficient," says Chen. "However, during the research we found the solar cell phenomenon [had] disappeared." Instead, the test material showed high gain photoconductivity, indicating potential use as a photo sensor.'"
This is fairly old news. We've been seeing the same stuff in our lab for about 8 years (also came across it during Quantum Dot research). It's been very hard to characterize. Cool stuff. Since you have x, y, and z resolution when you're "writing" to the photosensitive material, and these spots can be diffraction limited in size, you can imagine the storage density of read-only optical media for this.
I couldn't find it in the archive because the search tool is down, but Schlock Mercenary by Howard Tayler once made the observation that great discoveries are less "Eureka!" and more "Hey, that's funny."
