What is the lattice structure of silicon?

Silicon has the diamond cubic crystal structure with a lattice parameter of 0.543 nm. The nearest neighbor distance is 0.235 nm. The diamond cubic crystal structure has an fcc lattice with a basis of two silicon atoms.

What is the lattice structure of vanadium?

Vanadium, V The electronic configuration of vanadium is (Ar)(3d)3(4s)2, and it has an atomic radius of 0.134 nm. At room temperature vanadium has a body cenetred cubic crystal structure with a basis of one atom per lattice point. The lattice parameter is 0.303 nm. Vanadium has a Young’s modulus of 130 GPa.

What is the structure of silicon and germanium?

Diamond Cubic Crystal Structure Silicon and Germanium are examples of covalent crystals. In these solids the atoms are linked to each other by covalent bonds rather than by electrostatic forces or by delocalized valence electrons that work in metals almost like a “glue”.

Is nickel FCC or BCC?

Some of the metals that have the fcc structure include aluminum, copper, gold, iridium, lead, nickel, platinum and silver.

Which is better germanium or silicon?

Why is silicon usually preferred to germanium in the manufacture of semiconductor devices? Silicon is abundant on the earth’s surface and therefore cheaper than germanium. The PIV (Peak Inverse Voltage) rating of silicon is much higher than germanium and therefore can withstand much higher temperatures than germanium.

What is difference between germanium and silicon?

Silicon is a chemical element with atomic number 14 and chemical symbol Si while germanium is a chemical element with atomic number 32 and chemical symbol is Ge. The key difference between silicon and germanium is that Germanium has d electrons, but Silicon does not have any d electrons.
