Theory of high bias Coulomb Blockade in ultrashort molecules
Bhaskaran Muralidharan, Avik W Ghosh, Swapan K Pati +1
We point out that single electron charging effects such as Coulomb Blockade (CB) and high-bias staircases play a crucial role in transport through single ultrashort molecules. A tr…
Probing electronic excitations in molecular conduction
B. Muralidharan, A. W. Ghosh, S. Datta
We identify experimental signatures in the current-voltage (I-V) characteristics of weakly contacted molecules directly arising from excitations in their many electron spectrum. Th…
A Theoretical Investigation of Surface Roughness Scattering in Silicon Nanowire Transistors
Jing Wang, Eric Polizzi, Avik Ghosh +2
In this letter, we report a three-dimensional (3D) quantum mechanical simulation to investigate the effects of surface roughness scattering (SRS) on the device characteristics of S…
Charging induced asymmetry in molecular conductors
F. Zahid, A. W. Ghosh, M. Paulsson +2
We investigate the origin of asymmetry in various measured current-voltage (I-V) characteristics of molecules with no inherent spatial asymmetry, with particular focus on a recent…
Silicon-based molecular electronics
T. Rakshit, G-C. Liang, A. W. Ghosh +1
Molecular electronics on silicon has distinct advantages over its metallic counterpart. We describe a theoretical formalism for transport through semiconductor-molecule heterostruc…
Molecular conduction: paradigms and possibilities
A. W. Ghosh, S. Datta
We discuss the factors that determine the overall shape and magnitude of the current-voltage (I-V) characteristics of a variety of molecular conductors sandwiched between two metal…
