  Serenity inside Sells ventures, lease options and charters from Texas By David Vincent Bell Hirsch Frank Zappa - Valley Girl Valleytronics (from valley and electronics) is an experimental area in semiconductors that exploits local minima ("valleys") in the electronic band structure . Certain semiconductors have multiple "valleys" in the electronic band structure of the first Brillouin zone , and are known as multivalley semiconductors. [1] [2] Valleytronics is the technology of control over the valley degree of freedom, a local maximum/minimum on the valence / conduction band , of such multivalley semiconductors. The term was coined in analogy to spintronics . While in spintronics the internal degree of freedom of spin is harnessed to store, manipulate and read out bits of information, the proposal for valleytronics is to perform similar tasks using the multiple extrema of the band structure, so that the information of 0s and 1s would be stored as diff
