What is gallium phosphide? For those of you who are not familiar with this, here's the introduction:
Gallium nitride crystal structure of sphalerite, lattice constant 5.447 + / - 0.06, chemical bond and the mixture of covalent bond, the ionic bond component is about 20%, at 300 k energy gap of 2.26 eV, belong to indirect transition type semiconductor. Gallium phosphide and other broadband gap Ⅲ - Ⅴ family compound semiconductor (e.g., GaAS, InP), the same can by introducing deep center make the Fermi level close to the central band gap, such as adding impurity elements such as chromium, iron, oxygen can be half insulating materials. No non-doped semi-insulation materials are currently available.
Synthetic compound semiconductor materials. Appearance: orange transparent crystal. Gallium nitride is a kind of by Ⅲ elements gallium (Ga) and V elements phosphorus (P) synthetic Ⅲ - V compound semiconductor materials.
