Molecular Electronics: From Physics to Computing
Yongqiang Xue, Mark A. Ratner
Even if Moore's Law continues to hold, it will take about 250 years to fill the performance gap between present-day computer and the ultimate computer determined from the laws of p…
Electron transport in semiconducting carbon nanotubes with hetero-metallic contacts
Yongqiang Xue, Mark A. Ratner
We present an atomistic self-consistent study of the electronic and transport properties of semiconducting carbon nanotube in contact with metal electrodes of different work functi…
Theoretical Principles of Single-Molecule Electronics: A Chemical and Mesoscopic View
Yongqiang Xue, Mark A. Ratner
Exploring the use of individual molecules as active components in electronic devices has been at the forefront of nanoelectronics research in recent years. Compared to semiconducto…
Mechanical modulation of single-electron tunneling through molecular-assembled metallic nanoparticles
Yongqiang Xue, Mark A. Ratner
We present a microscopic study of single-electron tunneling in nanomechanical double-barrier tunneling junctions formed using a vibrating scanning nanoprobe and a metallic nanopart…
Local-field effects in current transport through molecular electronic devices: Current density profiles and local non-equilibrium electron distributions
Yongqiang Xue, Mark A. Ratner
We analyze non-equilibrium current transport in molecular electronic devices, using as an example devices formed by two terphenyl dithiol molecules attached to gold electrodes. Usi…
Scaling analysis of electron transport through metal-semiconducting carbon nanotube interfaces: Evolution from the molecular limit to the bulk limit
Yongqiang Xue, Mark A. Ratner
We present a scaling analysis of electronic and transport properties of metal-semiconducting carbon nanotube interfaces as a function of the nanotube length within the coherent tra…
