      Shanmugaratnam, Sivagowri; Velauthapillai, Dhayalan; Ravirajan, Punniamoorthy; Christy, Alfred Antony; Shivatharsiny, Yohi (Journal article; Peer reviewed, 2019)
      Transition metal chalcogenides have intensively focused on photocatalytic hydrogen production for a decade due to their stronger edge and the quantum confinement effect. This work mainly focuses on synthesis and hydrogen ...
    • First-Principle Calculation of High Absorption-TlGaTe2 for Photovoltaic Application 

      Rasukkannu, Murugesan; Velauthapillai, Dhayalan; Vajeeston, Ponniah (Journal article; Peer reviewed, 2019)
      We use first-principle calculations based on hybrid functional and the Bethe-Salpeter equation method to investigate the electronic and optical properties of dichalcogenide TlGaTe2. Based on theoretical studies, TlGaTe2 ...
    • Properties of novel non-silicon materials for photovoltaic applications: A first-principle insight 

      Rasukkannu, Murugesan; Velauthapillai, Dhayalan; Bianchini, Federico; Vajeeston, Ponniah (Journal article; Peer reviewed, 2018)
      Due to the low absorption coefficients of crystalline silicon-based solar cells, researchers have focused on non-silicon semiconductors with direct band gaps for the development of novel photovoltaic devices. In this study, ...
