There are number of film deposition techniques known, but few of the most utilized ones are briefly discussed above for the sake of completeness, as it is the aim of the present paper.
Typically synthesized polycrystalline films exhibit a high recombination rate due to existence of excessive grain boundaries and oxygen vacancies.
The properties are greatly affected by the grain size and their distribution, chemical composition of constituent phases.
Such grain boundaries, hetero-phases, inter-phases or inter-surface state interactions greatly affect their performance [1].
Impurity doping is largely intended to improve electrical conduction, by raising the number of charge carriers and/or by increasing the carrier mobility.

It is clearly seen that the system consists of several grains, namely the system is in a polycrystalline state.
This may be due to the large number of defects included in these nanoparticles.

In the machining process, tool materials should have high wear resistance because the silicon grains in the alloy generate abrasive action on the tool and make machining relatively difficult [3].

Experiment The TiO2 target was prepared from nanoparticles (anatase, 99.7% purity, Aldrich Chem.) of a grain size < 25 nm with the addition of organic compound - polyethylene glycol used as a binder.
The number of laser pulses applied for sample preparation typically did not exceed 72 000.

Mixing Machine When the grain size and shape distribution are affirmed, the particles of different classes can be mixed by mixing machine.
A large number of gases are absorbed by these pores.

As opposed to formation of a single localized crack, multiple cracking manifests itself by generation of a large number of distributed matrix cracks bridged by fibers [3][4].
F-110 fine silica sand from US silica with a maximum grain size of 250µm and a mean size of 110µm was adopted in the mixture.

There have been a significant number of published papers focusing on the influence of electrodeposition parameters on Ms and Hc of Fe-Co films [7-11].
As can be seen from the SEM graphs, the grain size of Fe52Co48 film deposited at 15 oC is much larger than that at 30 oC, while the Fe52Co48 film deposited at 30 oC is uniform and compact compared to that at 15 oC.

Some examples of intrinsic defects are vacancy, interstitial, dislocation, grain boundary, stacking fault, etc.
Thus the number of dipoles decreases with the increase of lamp black carbon doping and we may say that the mixture of lamp black carbon and paraffin wax produces some conducting paths within it for which the specimen looses its dielectric property.

The grain size of 1640 oC brazed joint is larger than those of 1580 and 1610 oC brazed ones.

As a result of comparative analysis for number of analyzed molding results about AISI 304 stainless steel depending on various conditions, a angle of incline(β) 7.5˚ and wagon velocity(Vp) 8mm/s are set as optimal value.
So, when velocity of thermal activated mechanism quicken, slip of grain boundary is activated by molding temperature and cyclic load.
