On the Validity of the Parabolic Effective-Mass Approximation for the Current-Voltage Calculation of Silicon Nanowire Transistors
Jing Wang, Anisur Rahman, Avik Ghosh +2
This paper examines the validity of the widely-used parabolic effective-mass approximation for computing the current-voltage (I-V) characteristics of silicon nanowire transistors (…
Performance Evaluation of Ballistic Silicon Nanowire Transistors with Atomic-basis Dispersion Relations
Jing Wang, Anisur Rahman, Avik Ghosh +2
In this letter, we explore the bandstructure effects on the performance of ballistic silicon nanowire transistors (SNWTs). The energy dispersion relations for silicon nanowires are…
Effect of anharmonicity of the strain energy on band offsets in semiconductor nanostructures
Olga L. Lazarenkova, Paul von Allmen, Fabiano Oyafuso +2
Anharmonicity of the inter-atomic potential is taken into account for the quantitative simulation of the conduction and valence band offsets for highly-strained semiconductor heter…
Effect of wetting layers on the strain and electronic structure of InAs self-assembled quantum dots
Seungwon Lee, Olga L. Lazarenkova, Fabiano Oyafuso +2
The effect of wetting layers on the strain and electronic structure of InAs self-assembled quantum dots grown on GaAs is investigated with an atomistic valence-force-field model an…
Effect of electron-nuclear spin interactions on electron-spin qubits localized in self-assembled quantum dots
Seungwon Lee, Paul von Allmen, Fabiano Oyafuso +2
The effect of electron-nuclear spin interactions on qubit operations is investigated for a qubit represented by the spin of an electron localized in a self-assembled quantum dot. T…
