Atlanta HA (SPX) Apr 16, 2014One of the great problems in physics is the detection of electromagnetic radiation - that is, light - which lies outside the small range of wavelengths that the human eye can see. Think X-rays, for example, or radio waves. Now, researchers have discovered a way to use existing semiconductors to detect a far wider range of light than is now possible, well into the infrared range.
