Amorphous hydrogenated boron carbide is a complex disordered semi-insulating material being studied for neutron detection applications owing to its high thermal neutron absorption cross-section and high resistivity. Optimizing its charge transport properties, including charge carrier mobility, lifetime, and mobility-lifetime product, will be essential to successful detector implementation. Tuning these properties requires a clear understanding of the disorder in this solid, as well as charge injection and hopping via localized states, and how these phenomena lead to difficulties in experimental design as well as analysis of charge transport measurements. This contribution will present an overview of the challenges and nontrivialities in establishing electrical contacts and determining charge transport properties introduced by the disorder in the material, and our approaches to measurement and analysis.
