We’ve long used large portions of various frequencies and their wavelengths (known as the electromagnetic spectrum) for diverse technologies, such as X-rays and radios. But there is a gap in this spectrum that's been largely out of reach. This gap, known as the terahertz gap, is located between radio waves and infrared radiation and accounts for two parts of the spectrum we use in everyday technologies – from cell phones to TV remotes.
Now Stanford physicists have realized a theory about this gap made decades ago by the late Nobel laureate, and Stanford professor, Felix Bloch, and published their findings recently in Science. Bloch suggested that a specially structured material that allowed electrons to oscillate in a particular way might be able to conduct these sought-after terahertz signals.
Moore Foundation grantee and Stanford physics professor, David Goldhaber-Gordon, may have developed materials that enable these oscillations which could pave the way for significant improvements in technologies from solar cells to airport scanners.
