1. Enhanced gettering of gold at end-of-range defects in high energy ion implanted silicon

Satyabrata Mohapatra

Volume 8, Issue 10 , October 2017, , Pages 999-1003

  We report on the gettering behavior of Au at end-of-range (EOR) defects in float-zone grown Si(111), implanted with 1.5 MeV Au 2+ ions at room temperature. The effects of implantation dose and annealing temperature on the thermal evolution of gettering behavior of EOR defects have been investigated using ...  Read More

2. Assessing the linear and planer micro-structural defects in SnO2 Nanoparticles through high resolution transmission electron microscopy (HRTEM)

Shrabani Mondal; Rashmi Madhuri; Prashant K. Sharma

Volume 8, Issue 9 , September 2017, , Pages 927-931

  This letter assesses the origin of linear and planer micro-structural defects in SnO2 nanoparticles through high resolution transmission electron microscopy (HRTEM). For the purpose, SnO2 nanoparticles of size 5-15 nm are synthesized by chemical co-precipitation followed by calcinations. In the low temperature ...  Read More

3. Core/shell Nanostructures Due To Ce Into CoFe2O4 Induce Lattice And Vibrational Defects For Magnetic And Dielectric Enhancement

Kuldeep Chand Verma; R.K. Kotnala

Volume 7, Issue 8 , August 2016, , Pages 622-629

  We reported the Core/Shell structures of CoFe2-xCexO4 (CFCeO) nanoparticles were prepared by a chemical combustion method. The Rietveld refinement of X-ray diffraction pattern results into CoFe2O4 spinel structure and thevariation in lattice parameters have been found with doping of Ce ions. Transmission ...  Read More

4.  Electric Field-effect-assisted Persistent Photoconductivity In CZTS

Nadarajah Muhunthan; Om P. Singh; Vidya N. Singh; Kedar N. Sood

Volume 6, Issue 4 , April 2015, , Pages 290-293

  Copper zinc tin sulfide (CZTS) thin film was deposited by co-sputtering metal targets and post-deposition sulfurization in H2S. Temperature-dependent electrical conductivity and photoconductivity effects in CZTS are studied. The low temperature electrical conductivity measurement shows acceptor level ...  Read More

5. Native Defects And Optical Properties Of Ar Ion Irradiated ZnO

S. Pal; A. Sarkar; D. Sanyal; T. Rakshit; D. Kanjilal; P. Kumar; S. K. Ray; D. Jana

Volume 6, Issue 4 , April 2015, , Pages 365-369

  1.2 MeV Argon (Ar) ion irradiation turns white coloured ZnO to yellowish (fluence 1 × 10 14 ions/cm 2 ) and then reddish brown (1 × 10 14  ions/cm 2 ). At the same time the material becomes much more conducting and purely blue luminescent for the highest fluence of irradiation. To get ...  Read More
