In this paper, the propagation properties of Surface Plasmon Polariton mode in Metal-Insulator-Metal waveguide are presented. An additional thin metallic film is inserted inside the insulator for higher confinement. Silver (Ag) has been taken as the metal and air, gallium lanthanum sulphide (GLS) and aluminum gallium arsenide (AlGaAS) as the insulators for the construction of the waveguide. Fin...

This paper investigated the wear mechanism of diamond during atomic force microscope (AFM) tip-based nanomachining Gallium Arsenide (GaAs) using molecular dynamics (MD) simulations. The elastic–plastic deformation at apex tip was observed Meanwhile, a transition from its initial cubic lattice structure sp3 hybridization to graphite sp2 revealed. Graphitization was, therefore, found be dominant ...

Emerging trend in semiconductor nanotechnology motivates to design various crystalline nanotubes. The structural and electronic transport properties of single walled zigzag Gallium Arsenide nanotubes have been investigated using Density Functional Theory (DFT) and Non-Equilibrium Green’s Function (NEGF) based First Principle formalisms. Structural stability and enhanced electronic transmission ...
