Electron trapping harnessed to make light sensors

Traps. Whether you're squaring off against the Empire or trying to wring electricity out of sunlight, they're almost never a good thing. But sometimes you can turn that trap to your advantage. A team from the University of Nebraska-Lincoln, working with researchers at the National Institute of Standards and Technology, has shown that electron-trapping defects that are typically problematic in solar cells can be an asset when engineering sensitive light detectors.
