Molecular Dynamics and FEM Modeling of Composites Having High Thermal Conductivity

Sumit Sharma; Pramod Kumar; Ajay Kumar Diwakar

Volume 11, Issue 9 , September 2020, , Pages 1-7


  Nowadays there is a requirement of material that has high thermal conductivity as well as suitable electric insulating properties. Such materials are required in industries where thermal management is desirable but electrical conductivity is not required, such as substrates for electronic components ...  Read More

Transient reflection spectra in topological nanocrystals of Bi2Se3, Bi2Te3, Bi2Te2Se

Faizan Ahmad; Rashmi Singh; Rachana Kumar; Mukesh Jewariya; Chandra Shekhar; Naresh Kumar; Pramod Kumar

Volume 8, Issue 4 , April 2017, , Pages 423-427


  The wavelength and time delay dependent reflection spectra of nano crystals Bi2Se3, Bi­2Te3 and Bi­2Te2Se were studied for ultrafast dynamics, using pump and probe spectroscopy. We observed only one transient peak for Bi2Se3 below 600nm, which decreases linearly with time delay. Three transient ...  Read More

Heat Capacity, Magnetic And Lattice Dynamic Properties Of Pseudo-two Dimensional: M2Fe2O(AsO4)2 [M=K, K0.79Cs0.21 and Rb] Compounds

Pramod Kumar; Rashmi Singh; L. D. Sanjeewa; Rachana Kumar

Volume 7, Issue 12 , December 2016, , Pages 964-970


  In this paper, structural, magnetic and heat capacity of M2Fe2O(AsO4)2 compounds have been reported. Most interestingly, the magnetization at very low fields  a complete negative magnetization was observed in both field cooling and zero field cooling in K2Fe2O(AsO4)2 and Rb2Fe2O(AsO4)2 compounds ...  Read More

Unusual Magnetism In TbRu2Ge2 Compound

Rashmi Singh; Puneet Jain; Rachana Kumar; Pramod Kumar

Volume 7, Issue 10 , October 2016, , Pages 813-816


  Magnetic properties of TbRu2Ge2 were studied. TbRu2Ge2 shows unusual magnetism, i.e. at low field it shows frustration (like spin glass) and at high field, this frustration starts to disappear. It has been found that TbRu2Ge2 has a TN of 37K. To confirm the frustration in TbRu2Ge2, AC susceptibility ...  Read More
