Gallium arsenide (GaAs) based microaccelerometers are being developed for guidance and navigation subsystems, and various microsensor systems. The microaccelerometer is a microelectromechanical system (MEMS) micromachined on top of GaAs substrate or GaAs integrated cirwits. The MEMS accelerometer is integrated on the same chip as the GaAs readout circuit and the GaAs analog to digital converter...

Positron Annihilation techniques have been used to investigate two important defects that occur naturally in semi-insulating (SI) Gallium arsenide. The growth and assessment of SI GaAs and the application of PA to defect analysis of this important material are reported.

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 ...

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 ...
