New Approach Using Nanoparticle Alloys Allows Heat to Be Focused or Reflected Just Like Electromagnetic WavesNew Approach Using Nanoparticle Alloys Allows Heat to Be Focused or Reflected Just Like Electromagnetic Waves

15/01/2013

 

An MIT researcher has developed a technique that provides a new way of manipulating heat, allowing it to be controlled much as light waves can be manipulated by lenses and mirrors. The approach relies on engineered materials consisting of nanostructured semiconductor alloy crystals. Heat is a vibration of matter — technically, a vibration of the atomic lattice of a material — just as sound is. Such vibrations can also be thought of as a stream of phonons — a kind of «virtual particle» that is analogous to the photons that carry light. The new approach is similar to recently developed photonic crystals that can control the passage of light, and phononic crystals that can do the same for sound.
