  • Multipodal formation of Tio2 nanotubes using anodization 
    Naduvath, Johns; Bhargava, Parag; Mallick, Sudhanshu (American Institute of Physics Inc., 2019-03-22)
    The titanium dioxide nanotube arrays with large pore size and multipodal nature have many applications including solar cells applications, three terminal devices, drug delivery and other light harvesting applications. A ...
  • Lead free, air stable perovskite derivative Cs2SnI6 as HTM in DSSCs employing TiO2 nanotubes as photoanode 
    Peedikakkandy, Lekha; Naduvath, Johns; Mallick, Sudhanshu; Bhargava, Parag (ELSEVIER, 2018-12)
    Cs2SnI6 is an air-stable and non-toxic perovskite variant photovoltaic material which exhibits p-type conductivity under doped conditions. In this work, we report the synthesis and stability studies of Cs2SnI6 towards its ...
  • A simple method to fabricate metal doped TiO2 nanotubes 
    K, Aijo John; Naduvath, Johns; Remillard, Stephen K; Shaji, Sadasivan; DeYoung, Paul A; Kellner, Zachary T; Mallick, Sudhanshu; Thankamoniamma, Manju; Okram, Gunadhor S; Philip, Rachel Reena (ELSEVIER, 2019-07-01)
    A simple electrochemical method for effective doping of TiO2 nanotubes with metals is presented here. The doping is done in a two-stage cost effective process and is found to result in uniform doping concentration, without ...
  • Electrochemical Synthesis of Novel Zn-Doped TiO2 Nanotube/ZnO Nanoflake Heterostructure with Enhanced DSSC Efficiency 
    K, Aijo John; Naduvath, Johns; Mallick, Sudhanshu; Pledger, Jacob W; Remillard, SK; DeYoung, PA; Thankamoniamma, Manju; Shripathi, T; Philip, Rachel Reena (Springer, 2016-07-02)
    The paper reports the fabrication of Zn-doped TiO2 nanotubes (Zn-TONT)/ZnO nanoflakes heterostructure for the first time, which shows improved performance as a photoanode in dye-sensitized solar cell (DSSC). The layered ...
  • Effect of anionic concentration on the structural and optical properties of nanostructured ZnS thin films 
    Safeera, TA; Johns, N; Anila, EI (Elsevier, 2016-08)
    Nanostructured Zinc Sulfide (ZnS) thin films with wurtzite structure were prepared by chemical spray pyrolysis method at low temperature. The effect of sulfur concentration on the structural and optical properties of ZnS ...
