Ph.D. student in physics in collaboration with a faculty member of the University of Guilan designed and constructed an innovative device for the deposition of thin films. In this device, which is a "reactive magnetic electro-thermophoresis coating device", an innovative technique called electro-thermophoresis is used, where electrophoresis and thermophoresis techniques are used simultaneously.



This device was created by Mr. Majid Safari Sakhawat, a Ph.D. student at the University of Guilan, with the cooperation of Dr. Farhad Esmaili Qudsi, a faculty member of the University of Guilan; it was designed and invented in the Faculty of Science of this university, and it is equipped with a gasification system in the TB environment. Among the applications of this innovative method, we can point out the creation of films with a very wide thickness range from a few nanometers to several tens of micrometers for making different parts. The features of the invented device are:

The ability to produce a uniform electric field

The possibility of creating all kinds of sinusoidal, triangular, and square pulse electric fields from 1 Hz to 400 kHz

Testing electrochromic parts

Using a controllable temperature gradient

Using a controllable magnetic field to increase deposition efficiency

Gas injection into the deposition cell containing the cell for the reactive electro-thermophoresis process

This achievement has been published in an article ( in the Journal of Materials Research (JMRS) with the ISI index.
