Silicon Atomic Quantum Dots Enable Beyond-CMOS Electronics
Robert A. Wolkow, Lucian Livadaru, Jason Pitters +5
We review our recent efforts in building atom-scale quantum-dot cellular automata circuits on a silicon surface. Our building block consists of silicon dangling bond on a H-Si(001)…
Conductivity of Si(111) - 7 x 7: the role of a single atomic step
Bruno V. C. Martins, Manuel Smeu, Hong Guo +1
The Si(111) - 7 x 7 surface is one of the most interesting semiconductor surfaces because of its complex reconstruction and fascinating electronic properties. While it is known tha…
Characterizing the rate and coherence of single-electron tunneling between two dangling bonds on the surface of silicon
Zahra Shaterzadeh-Yazdi, Lucian Livadaru, Marco Taucer +4
We devise a scheme to characterize tunneling of an excess electron shared by a pair of tunnel-coupled dangling bonds on a silicon surface -- effectively a two-level system. Theoret…
Single Electron Dynamics of an Atomic Silicon Quantum Dot on the H-Si(100) 2x1 Surface
Marco Taucer, Lucian Livadaru, Paul G. Piva +4
Here we report the direct observation of single electron charging of a single atomic Dangling Bond (DB) on the H-Si(100) 2x1 surface. The tip of a scanning tunneling microscope is…
