Abstract
  Doping of cations into wide bandgap semiconductors is an effective method of increasing photocatalytic activity. This work aims to find out how dopant ions like Ag+, Cu2+ and Sn2+ affect the structural, optical and photocatalytic properties of Li2GeTeO6. The parent Li2GeTeO6 (LGTO) was synthesized by ...  Read More

Electrochemical Hydrogen Evolution Reaction Triggered by Co2xMo1-xS2 (x = 0. 0.05 and 0.1) in Acidic Medium

Aruna K Kunhiraman; Bradha Madhavan

Volume 12, Issue 8 , August 2021, , Pages 1-4

http://dx.doi.org/10.5185/amlett.2021.081655

Abstract
  Facile solvothermal route was adopted for the synthesis of Co2xMo1-xS2 with x = 0, 0.05 and 0.1. Higher HER activity was exhibited by x = 0.1 in Co doped MoS2, with a current density -140 mAcm -2 at an overpotential of -100 mV. At lower overpotential both the compositions exhibited almost same activity, ...  Read More

A First-principle Study Of The Optical Properties Of Pure And Doped LaNiO3

Tarun Kumar Kundu; Debolina Misra

Volume 7, Issue 5 , May 2016, , Pages 344-348

http://dx.doi.org/10.5185/amlett.2016.6105

Abstract
  Density Functional Theory (DFT) is employed to study the various optical properties of pseudo-cubic LaNiO3. As LaNiO3 is a strongly correlated material, conventional DFT like LDA or GGA and even GW approximation fail to describe, we have examined the optical spectra of this compound using GGA(PBE)+U ...  Read More
