What’s more, Ceramic particle reinforced metal matrix composite can be made to be functionally graded material(FGM) armor, as the wave impedance, elastic modulus and coefficient of thermal expansion of the FGM armor can change smoothly, the stress concentration existing in the interface of common composite armor materials will be greatly reduced.
Berezovski [4] etc studied the propagation of stress waves in functionally graded materials.

TCO materials have both electrical conduction (104 S cm-1) and optical transparency (>90%) in the visible region [5].
Almost all the materials vaporize a solid or liquid phase as neutral atoms or molecules.
The evaporation of materials is done in vacuum system which in most cases comprises a diffusion pump backed by rotary pump.

Therefore, many properties of these materials can be systematically described and understood in term of quantum confinement effects.
They have also discussed an essential issue in developing semiconductor devices for photo-voltaics and thermo-electrics is used to design materials with appropriate band gaps plus the proper positioning of dopant levels relative to the bands.
To determine the effective band gap of semiconductor materials we incorporate the effect of kinetic energy, coulomb interaction and correlation effect in band gap of bulk material.
