Orbital Stark Effect And Quantum Confinement Transition Of Donors In Silicon, Rajib Rahman, G P. Lansbergen, Seung H. Park, J Verduijn, Gerhard Klimeck, S Rogge, Lloyd Cl Hollenberg
Orbital Stark Effect And Quantum Confinement Transition Of Donors In Silicon, Rajib Rahman, G P. Lansbergen, Seung H. Park, J Verduijn, Gerhard Klimeck, S Rogge, Lloyd Cl Hollenberg
Birck and NCN Publications
Adiabatic shuttling of single impurity bound electrons to gate-induced surface states in semiconductors has attracted much attention in recent times, mostly in the context of solid-state quantum computer architecture. A recent transport spectroscopy experiment for the first time was able to probe the Stark shifted spectrum of a single donor in silicon buried close to a gate. Here, we present the full theoretical model involving large-scale quantum mechanical simulations that was used to compute the Stark shifted donor states in order to interpret the experimental data. Use of atomistic tight-binding technique on a domain of over a million atoms helped …
