Abstract
We successfully have grown high quality single crystals of CoSe by flux-free melt growth process. Structural and elemental analysis have been performed using X-ray diffraction (XRD) and energy dispersive X-ray spectroscopy (EDXS), respectively. The XRD patterns confirm hexagonal crystal structure of the compound with a P63/mmc space group. We have measured electrical resistivity of CoSe within the temperature range of 2–300 K. From the Bloch-Grṻneisen (BG) fitting of the resistivity data suggest for a dominant electron–phonon scattering in this system with a Debye temperature of 254 K. Magnetization measurements suggest that these are paramagnetic in nature.
