  • Intrinsic Rattler-Induced Low Thermal Conductivity in Zintl Type TlInTe2 
    Jana, Manoj K.; Pal, Koushik; Warankar, Avinash; MANDAL, PANKAJ; Waghmare, Umesh V.; Biswas, Kanishka (American Chemical Society, 2017-03)
    Understanding the nature of chemical bonding and lattice dynamics together with their influence on phonon-transport is essential to explore and design crystalline solids with ultralow thermal conductivity for various ...
  • Microscopic Origin of Piezoelectricity in Lead- Free Halide Perovskite: Application in Nanogenerator Design 
    Pandey, Richa; Gangadhar, S.B.; Grover, Shivani; SINGH, SACHIN KUMAR; Kadam, Ankur; OGALE, SATISHCHANDRA; Waghmare, Umesh V.; Rao, V. Ramgopal; Kabra, Dinesh (American Chemical Society, 2019-03)
    In this work, we report a lead-free hybrid halide perovskite system with a very high piezoelectric charge density for applications in nanogenerators. We use materials engineering by incorporation of formamidinium tin iodide, ...
  • Ultralow Thermal Conductivity in Chain-like TlSe Due to Inherent Tl+ Rattling 
    Dutta, Moinak; Matteppanavar, Shidaling; Prasad, Matukumilli V. D.; Pandey, Juhi; WARANKAR, AVINASH; MANDAL, PANKAJ; Soni, Ajay; Waghmare, Umesh V.; Biswas, Kanishka (American Chemical Society, 2019-12)
    Understanding the mechanism that correlates phonon transport with chemical bonding and solid-state structure is the key to envisage and develop materials with ultralow thermal conductivity, which are essential for efficient ...
