Quantum effects determine transport in emerging nanoelectronic devices. At the same time, scattering is still important and may control current at room temperature. A Wigner function based approach, which accounts for the interplay between coherent quantum effects and dissipative scattering effects, is presented. The Wigner equation is solved by means of an advanced Monte Carlo technique. Influ...
Silicene is a monolayer allotrope of silicon atoms arranged in a honeycomb structure with massless Dirac fermion characteristics similar to graphene. It merits development of silicon-based multifunctional nanoelectronic and spintronic devices operated at room temperature because of strong spin-orbit coupling. Nevertheless, until now, silicene could only be epitaxially grown on conductive substr...
The self-assembly of nanoelectronic devices provide an opportunity to achieve unprecedented density and manufacturing scale in the post-Moore’s Law era. Bottom-up DNA self-assembly has emerged as a promising technique towards achieving this vision and it has been used to demonstrate precise patterning and functionalisation at resolutions below 20 nm. However, a lack of understanding of fabricat...
DNA is a material that has the potential to be used in nanoelectronic devices as an active component. However, the electronic properties of DNA responsible for its conducting behaviour remain controversial. Here we use a self-consistent quantum molecular dynamics method to study the effect of DNA structure and base sequence on the energy involved when electrons are added or removed from isolate...
Quantum dot cellular automata is an emerging nanoelectronic computational architecture which has the potential of faster speed, smaller size and minimum power consumption compared to transistor-based technology. In QCA, binary information are encoded as electronic charge configuration of a cell. Fundamental unit in building of QCA circuit is a QCA cell. A QCA cell is an elementary building bloc...
With the high demand for nanoelectronic devices, extensive research has focused on the use of single walled carbon nanotubes (CNTs) due to their high electron carrier mobility, large tensile strength, and single nanometer dimensions. Despite their promise, however, their applicability has been greatly hindered by the inherent difficulties of both separating nanotubes of different chiralities an...
