Charge Pumping Through a Single Donor Atom
G. C. Tettamanzi, R. Wacquez, S. Rogge
Presented in this paper is a proof-of-concept for a new approach to single electron pumping based on a Single Atom Transistor (SAT). By charge pumping electrons through an isolated…
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…
Reply on the comment on the paper "Superconducting transition in Nb nanowires fabricated using focused ion beam"
G. C. Tettamanzi, A. Potenza, S. Rubanov +2
In this communication we present our response to the recent comment of A. Engel regarding our paper on FIB- fabricated Nb nanowires (see Vol. 20 (2009) Pag. 465302). After further…
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…
