Ferromagnet proximity effects and magnetoresistance of bilayer graphene
Y. G. Semenov, K. W. Kim, J. M. Zavada
A drastic modification of electronic band structure is predicted in bilayer graphene when it is placed between two ferromagnetic insulators. Due to the exchange interaction with th…
Graphene based spin field effect transistor
Y. G. Semenov, K. W. Kim, J. M. Zavada
A spin field effect transistor (FET) is proposed by utilizing a graphene nanoribbon as the channel. Similar to the conventional spin FETs, the device involves ferromagnetic metals…
Correlation of phonon decay with spin phase diffusion of localized electrons
Y. G. Semenov, K. W. Kim
A spin decoherence mechanism is proposed for localized electrons. The irregular phonon phase disturbances originated from phonon relaxation can influence electron spin precession w…
Anisotropy of heavy hole spin splitting and interference effects of optical polarization in semiconductor quantum wells subjected to an in-plane magnetic field
Yu. G. Semenov, S. M. Ryabchenko
Strong effects of optical polarization anisotropy observed previously in the quantum wells subjected to the in-plane magnetic field arrive at complete description within microscopi…
