It is established that at temperatures T<200K hopping conductivity with variable hopping length exists across natural layers of undoped and doped (0.2 and 0.4at% Sn) InSe single crystals in a constant electric field. The density of states near the Fermi level (NF=5.36⋅1018–1.72⋅1019eV−1⋅cm−3), the energy spread of the states (ΔE=0.028–0.040eV), the localization radius (a=58Å), and the average hopping length (Rav=99.5–130Å) in the temperature interval 100–200K are evaluated.
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.
