Donor Wavefunctions in Si Gauged by STM Images
A. L. Saraiva, J. Salfi, J. Bocquel +5
The triumph of effective mass theory in describing the energy spectrum of dopants does not guarantee that the model wavefunctions will withstand an experimental test. Such wavefunc…
Interplay between quantum confinement and dielectric mismatch for ultra-shallow dopants
J. A. Mol, J. Salfi, J. A. Miwa +2
Understanding the electronic properties of dopants near an interface is a critical challenge for nano-scale devices. We have determined the effect of dielectric mismatch and quantu…
Magnetic Field Probing of an SU(4) Kondo Resonance in a Single Atom Transistor
G. C. Tettamanzi, J. Verduijn, G. P. Lansbergen +4
Semiconductor nano-devices have been scaled to the level that transport can be dominated by a single dopant atom. In the strong coupling case a Kondo effect is observed when one el…
Drain current modulation in a nanoscale field-effect-transistor channel by single dopant implantation
B. C. Johnson, G. C. Tettamanzi, A. D. C. Alves +9
We demonstrate single dopant implantation into the channel of a silicon nanoscale metal-oxide-semiconductor field-effect-transistor. This is achieved by monitoring the drain curren…
Heterointerface effects on the charging energy of shallow D- ground state in silicon: the role of dielectric mismatch
M. J. Calderon, J. Verduijn, G. P. Lansbergen +3
Donor states in Si nanodevices can be strongly modified by nearby insulating barriers and metallic gates. We report here experimental results indicating a strong reduction in the c…
Coherent transport through a double donor system in silicon
J. Verduijn, G. C. Tettamanzi, G. P. Lansbergen +3
Quantum coherence is of crucial importance for the applicability of donor based quantum computing. In this Letter we describe the observation of the interference of conduction path…
