Donors in Ge as Qubits: Establishing Physical Attributes
A. Baena, A. L. Saraiva, Marcos G. Menezes +1
Quantum electronic devices at the single impurity level demand an understanding of the physical attributes of dopants at an unprecedented accuracy. Germanium-based technologies hav…
Theory of one and two donors in Silicon
A. L. Saraiva, A. Baena, M. J. Calderón +1
We provide here a roadmap for modeling silicon nano-devices with one or two group V donors (D). We discuss systems containing one or two electrons, that is, D^0, D^-, D_2^+ and D_2…
Impact of the valley degree of freedom on the control of donor electrons near a Si/SiO_2 interface
A. Baena, A. L. Saraiva, Belita Koiller +1
We analyze the valley composition of one electron bound to a shallow donor close to a Si/barrier interface as a function of an applied electric field. A full six-valley effective m…
Effect of strain on the orbital and magnetic ordering of manganite thin films and their interface with an insulator
A. Baena, L. Brey, M. J. Calderon
We study the effect of uniform uniaxial strain on the ground state electronic configuration of a thin film manganite. Our model Hamiltonian includes the double-exchange, the Jahn-T…
