Valley interference effects on a donor electron close to a Si/SiO2 interface
M. J. Calderon, Belita Koiller, S. Das Sarma
We analyze the effects of valley interference on the quantum control and manipulation of an electron bound to a donor close to a Si/SiO2 interface as a function of the valley-orbit…
Magnetoresistance in an all-manganite heterostructure
J. Salafranca, M. J. Calderon, L. Brey
We study the magnetic and transport properties of all-manganite heterostructures consisting of ferromagnetic metallic electrodes separated by an antiferromagnetic barrier. We find…
Reliability of the Heitler-London approach for the exchange coupling between electrons in semiconductor nanostructures
A. L. Saraiva, M. J. Calderon, Belita Koiller
We calculate the exchange coupling J between electrons in a double-well potential in a two-dimensional semiconductor environment within the Heitler-London (HL) approach. Two functi…
