Volume 7, Issue 2 , January 2025, Pages 39-48

https://doi.org/10.30473/jphys.2024.71403.1193

Abstract
  This paper has studied the electronic properties of PdS2 monolayers doped with substitutional 3d, 4d, and 5d transition metals (TMs). The findings indicate that when a Pd atom is replaced by 3d metals (Sc, Fe), 4d metals (Y, Ru, Rh), and 5d metals (Os) through doping, the Fermi level moves towards the ...  Read More

Study of Pristine and Ni-Doped ZnO Nanorods Synthesized by Pulse Laser Deposition

Ahmad Kamalianfar

Volume 7, Issue 2 , January 2025, Pages 49-54

https://doi.org/10.30473/jphys.2024.72650.1218

Abstract
  In this work, pristine and Ni-doped ZnO nanopods were deposited on silicon substrate by pulsed-laser deposition (PLD) machine. The morphogical, optical and electricl properties of Ni-doped ZnO nanopod films were examined using various techniques. SEM images of the surface of the samples showed that the ...  Read More

Mohammad Javad Maleki; Mohammad Soroosh; Ramakrishnan Rajasekar

Volume 7, Issue 2 , January 2025, Pages 55-63

https://doi.org/10.30473/jphys.2024.72509.1216

Abstract
  In this research, a new switch based on plasmonic ring resonator is proposed for the third telecommunication window. The designed structure consists of a ring in a silver region, the collar of which is barium oxide with silver nanoparticles, and it is considered a non-linear material. Placing the nonlinear ...  Read More
