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)…
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…
