● 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

B. Solution-Liquid-Solid Growth of Indium Phosphide Fibers from Organometallic Precursors: Elucidation of Molecular and Nonmolecular Components of the Pathway
Solution-phase organometallic syntheses of semiconductors are used for the growth of high-quality quantum dots,1-3 and are potentially useful for the deposition of semiconductor materials on thermally sensitive substrates such as polymers
electrostatic Coulombic force.
The exciton diffuses to around by chemical potential.
The lifetime <<1 nano seconds
The average distance <<10 nanometer.
The exciton diffuses to the interface between two layers
The exciton is saparated by an electron and a hole
(0.05~1.5eV)
1. The concentration of carrier is higher at interface than surrounding. So, the carrier diffus
