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…
