Iranian Nano-Scientists Improve Physical Properties of Computers

Iran | Posted on March 13th, 2010

"While the effect of silicon sublayer on physical properties of computer hardware has been neglected in previous theoretical studies, it is evaluated in our research," Saeed Jalali Asadabadi, the head researcher, said to the Iran Nanotechnology Initiative Council.

Elaborating the procedure of research, Jalali reiterated," All calculations were made by means of linear modified plane waves as well as local orbitals within the framework of density function theory. Silicon sublayer was first simulated by clouds-in-cells method and then deposited by thin zinc layers."

"Interatomic forces were relaxed to zero at an acceptable precision. Calculations of different physical quantities were made once with taking silicon sublayer into account and again without it resulting in revealing the effect of sublayer on size quantum effects," he added.

The results show that relative spin-orbit interaction effect is insignificant according to Rashba effect for thin layer Pb/Si(III) empirical results contrary to high atomic number of zinc. Moreover, sublayer effect on thin layers can be neglected when the strength of bond between sublayer atoms and the first thin layer in interface could be comparable to upper thin layers bonds.

On the other hand, the results imply that silicon sublayer's effect is important in the analysis of some of physical quantities and cannot be undermined.

The details of the present study are available at Computational Materials Science, volume 47, pages 584 to 592, 2009.
