Phys. Rev. Lett. 100, 156404 (2008) [4 pages]Proposal for a New Class of Materials: Spin Gapless SemiconductorsReceived 15 May 2007; revised 13 August 2007; published 18 April 2008 The concept of the spin gapless semiconductor in which both electron and hole can be fully spin polarized is proposed, and its possibility is presented on the basis of first-principles electronic structure calculations. Possible new physics and potential applications in spintronic devices based on the spin gapless semiconductors are discussed. © 2008 The American Physical Society URL:
