| Popis: | To quantify the effects of local magnetic fields on triple quantum dots, the Heisenberg Hamiltonian has been diagonalized for three electrons coupled via the exchange interaction. In particular, we have investigated different geometries of micro-magnets located on top of the triple dot in order to optimize the field gradient characteristics. In this paper, we focus on two geometries which are candidates for an addressable EDSR triple quantum dot device. © 2013 AIP Publishing LLC. 31st International Conference on the Physics of Semiconductors, ICPS 2012, 29 July 2012 through 3 August 2012, Zurich Series: AIP Conference Proceedings; no. 1566 |
