Solid Source
each cell is loaded with a charge material, usually a pure element like gallium or arsenic, which is solid at room temperature.
The gaseous atomic or molecular beam is generated by heating the charge in the effusion cell in the growth chamber.
The effective beam pressure or flow rate of the gas, called the beam flux, is varied by adjusting the effusion cell temperature.

● Definition of plasma
Plasma is one of the four fundamental states of matter, along with solid, liquid, and gas. It is an ionized gas consisting of a collection of charged particles, including ions, electrons, and neutral atoms or molecules. Plasma can be found naturally in the universe in the form of stars, lightning, and auroras, but it can also be artificially created and controlled for
