Doped Boron Carbide-Based Polymers: Fundamental Studies of a Novel Class of Materials for Enhanced Neutron Detection

Abstract

The overall goal of this basic research has been to develop novel, boron carbide-based polymers with novel chemical and electronic structures to enhance sensitivity to neutron detection. Films containing orthocarboranes with benzene, 1,4- diaminobenzene, or pyridine have been developed and characterized by photoemission and neutron voltaics studies at zero bias. Orthocarborane/pyridine films with pyridine:orthocarborane ratios>>1 deposited on n-type Si show greatly enhanced sensitivity to thermal neutrons, even with lower total B content, than pure boron carbide films, while remaining gamma-blind. The enhanced sensitivity indicates greatly enhanced charger collection efficiency in the carborane/pyridine films.
