The ternary chalcogenide AgBiSe2(ABS) crystal was grown using the Bridgman Stockbarger technique followed by XRD and Raman shift analysis to verify the structural properties of the ABS crystal. The temperature (300 K- 4.2 K) dependent resistivity (ρ) elucidates semiconductor behavior up to 109 K, and suddenly ρ decreases with decreasing temperature, elucidates metallic behavior up to 19 K but soon after ρ increases with further decrease in temperature owing to the impurities in the crystal. The charge defects caused by atomic vacancies as well as anti-site defects are thermodynamically induced and they have the potential to shift the Fermi energy level. The two lucid transitions at 109 K and 19 K in ρ(T) demonstrate consequent changes as a semiconductor-to-metal transition. The MR graph substantially displays the resistivebehavior with respect to the magnetic field applied and portraits the ‘U’ shape at 300K to the ‘V’shape at 4.2 K, proclaiming a sluggish to active resistive transition with respect to the magnetic
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
