Germanene, an allotrope of germanium which is a two dimensional material with sp 2 hybridization, has almost the same properties with graphene except for its buckled structure. In this study, germanium nanoribbon (GeNR) is use for it is still a new material for nanoscale level of research. In this paper, we investigate the effect of chirality on th...

The quality of epitaxial graphene on silicon (GOS) is negatively correlated with the residual stress of the 3C-SiC films grown on the Si substrates. This has been systematically demonstrated by use of a series of 3C-SiC films formed on Si(110) substrates with varied residual stress. The residual stress of the3C-SiC film and the grain size of graphe...

This study examines the nature of thermal transport properties of single layer two-dimensional honeycomb structures of silicon-germanene nanoribbon (SiGeNR), silicene nanoribbon (SiNR) and germanene nanoribbon (GeNR) which have not yet been characterized experimentally. SiGeNR, SiNR and GeNR are the allotropes of silicon-germanium, silicon and germ...

Silicene is a two-dimensional (2D) allotrope of silicon known to have a lower thermal conductivity than graphene; thus, more suitable for thermoelectric applications. This paper investigates the effect of hydrogenation on the thermal conductivity of silicene nanoribbon (SiNR) using equilibrium molecular dynamics (EMD) simulations. The simulations w...

Silicon-graphene nanoribbon (SiGNR), an allotrope of silicon carbide with sp 2 hybridization, gains interest nowadays in the world of two-dimensional materials. In this study, the thermal conductivity of SiGNR is investigated and compared to that of graphene nanoribbon (GNR) and silicene nanoribbon (SiNR). Molecular Dynamics using Tersoff potential...

A method to realize a novel hybrid orientations of Si surfaces, Si(111) on Si(110), has been developed by use of a Si(111)/3C-SiC(111)/Si(110) trilayer structure. This technology allows us to use the Si(111) portion for the n-type and the Si(110) portion for the p-type channels, providing a solution to the current drive imbalance between the two ch...

Detailed ab initio quantum mechanical calculations of a number of polythiophene oligomers are carried out to ascertain relative stability of structures bonding through α and β carbons. Energetics of dimers, trimers, tetramers, and pentamers with all possible linkages types are obtained from fully optimized geometries. This will determine the relati...
