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)…
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…
Modulation of Electrical Conduction Through Individual Molecules on Silicon by the Electrostatic Fields of Nearby Polar Molecules: Theory and Experiment
George Kirczenow, Paul G. Piva, Robert A. Wolkow
We report on the synthesis, scanning tunneling microscopy (STM) and theoretical modeling of the electrostatic and transport properties of one-dimensional organic heterostructures c…
Non-Local Conductance Modulation by Molecules: STM of Substituted Styrene Heterostructures on H-Terminated Si(100)
Paul G. Piva, Robert A. Wolkow, George Kirczenow
One-dimensional organic heterostructures consisting of contiguous lines of CF3- and OCH3-substituted styrene molecules on silicon are studied by scanning tunneling microscopy and a…
Linear Chains of Styrene and Methyl-Styrene Molecules and their Heterojunctions on Silicon: Theory and Experiment
George Kirczenow, Paul G. Piva, Robert A. Wolkow
We report on the synthesis, STM imaging and theoretical studies of the structure, electronic structure and transport properties of linear chains of styrene and methyl-styrene molec…
