P-N junction diode is simply a two-terminal device which allows the current to flow in one direction only.
-
The phenomenon of Raman scattering of light was experimentally observed in 1928 by Raman and Krishnan.
-
The process of converting unpolarized light into polarized light is known as polarization.
-
A predictable correlation of the amplitude and phase at any one point with another point is called coherence.

Semiconductors are materials that have conductivity between conductors and insulators.
