  1. Ultrafast Optical Measurements of Spin Polarization in Semiconductors

    29 Mar 2016 | | Contributor(s):: Vanessa Sih

    n this talk, I will describe optical techniques that can measure the magnitude and direction of spin-orbit fields and electrically-generated spin polarization in non-magnetic semiconductors and the modification of the electron spin precession frequency in a bulk semiconductor using an applied...

  6. Scattering in NEGF: Made simple

    09 Nov 2009 | | Contributor(s):: Dmitri Nikonov, Himadri Pal, George Bourianoff

    Formalism for describing electron-phonon scattering, surface scattering, and spin relaxation is dervied for the Keldysh non-equilibrium Green's functions (NEGF) method. Approximation useful for efficient numerical solution are described. The specific case of the nanoMOS simulator is...

  7. ECET 499N: Nanoelectronics

    30 Mar 2009 | | Contributor(s):: Supriyo Datta

    How does the resistance of a conductor change as we shrink its length all the way down to a few atoms? This is a question that has only become answerable during the last twenty years of work by experimentalists, leading to enormous progress in transistor development. This introductory lecture...
