Energy gap: 1.4ev at room temperature
Its charactistics are very closely related to those of germanium. This is under stable, since Gallium is the third column neighbour and arsenic is the fifth column neighbour of Gallium in the periodic table. The melting point is 13000C, makes the production of gallium arsenide of electronic grade and externally difficult one. Horizontal furnaces using zone refining technique have proved the best, but the resulting material is still is not competitive with silicon and germanium in the purity or structural perfection. It is used for Scotty diodes, light emitting diodes, gun diodes, and lasers.
It is the product of either change in an electric dipole with the distance separating them.
Newton''s rings are formed between a spherical lens surface and an optical flat. If the tenth bright ring of green light (545.1 nm) is 7.89 mm in diameter, what is the radius of cu

Q. Why does the sky appear blue in colour? As-per to the Rayleigh's scattering law the shorter wavelengths are scattered much more than the longer wavelengths. The blue look o
What is Gas Laws? Kinetic theory states that the speed of motion of the molecules in a substance decreases as the substance's temperature decreases. As well, the speed of motio
