1.Definizione di materiale in carburo di silicio

Parametro 1-1.reticolo

1-1.lattice parameter The lattice constant, or lattice parameter, refers to the constant distance between unit cells in a crystal lattice. Lattices in three dimensions generally have three lattice constants, referred to as a, b, and c. However, in the special case of cubic crystal structures, all of the constants are [...]

1-2. Sequenza di impilamento

1-2.Stacking Sequence If we are going to make a laminated structure, we must know the thickness of each ply and the angle of each ply traditionally in degrees defined from the top layer down.  

1-3.Durezza Mohs

1-3.Mohs Hardness Rough measure of the resistance of a smooth surface to scratching or abrasion, expressed in terms of a scale devised(1812)by the German mineralogist Friedrich Mohs. The Mohs hardness of a mineral is determined by observing whether its surface is scratched by a substance of known or defined hardness.


1-4.Density The mass density or density of a material is its mass per unit volume. The symbol most often used for density is ρ (the lower case Greek letter rho). Mathematically, density is defined as mass divided by volume:  

1-5. Coefficiente di espansione termica

1-5.Thermal Expansion Coefficient Thermal expansion is the tendency of matter to change in volume in response to a change in temperature. When a substance is heated, its particles begin moving more and thus usually maintain a greater average separation. Materials which contract with increasing temperature are rare; this effect is limited [...]

1-6.Indice di rifrazione

In optics the refractive index (or index of refraction) n of a substance (optical medium) is a number that describes how light, or any other radiation, propagates through that medium. Refractive index is the basic property of optical crystals, and it is an important parameter to study the properties of [...]


Nella fisica dello stato solido, un gap di banda, chiamato anche gap di energia o bandgap, è un intervallo di energia in un solido in cui non possono esistere stati di elettroni. Nei grafici della struttura elettronica a bande dei solidi, il gap di banda si riferisce generalmente alla differenza di energia (in elettronvolt) tra [...]

1-8. Guasto elettrico

1-8.Electrical Breakdown The term electrical breakdown or electric breakdown has several similar but distinctly different meanings. For example, the term can apply to the failure of an electric circuit. Alternatively, it may refer to a rapid reduction in the resistance of an electrical insulator that can lead to aspark jumping [...]
