Electric Field Control of Shallow Donor Impurities in Silicon
We present a tight-binding study of donor impurities in Si, demonstrating the
adequacy of this approach for this problem by comparison with effective mass
theory and experimental results. We consider the response of the system to an
applied electric field: donors near a barrier material and in the presence of
an uniform electric field may undergo two different ionization regimes
according to the distance of the impurity to the Si/barrier interface. We show
that for impurities ~ 5 nm below the barrier, adiabatic ionization is possible
within switching times of the order of one picosecond, while for impurities ~
10 nm or more below the barrier, no adiabatic ionization may be carried out by
an external uniform electric field. Our results are discussed in connection
with proposed Si:P quantum computer architectures.Comment: 18 pages, 6 figures, submitted to PR
