Abstract

This article reports an easy route synthesis of bulk polycrystalline TiSe2. Phase purity and microstructure are determined through powder X-ray diffraction (PXRD) and field emission scanning electron microscopy (FESEM) respectively. Vibrational modes of TiSe2 as being analyzed by Raman spectroscopy, show the occurrence of both Ag and Eg modes. Charge density wave (CDW) is observed in transport measurements of TiSe2 with hysteresis in cooling and warming measurements at around 180K. Further, studied TiSe2 showed negative magnetoresistance (MR) below the CDW and a small positive MR above the CDW.
