Neutron-detecting apparatuses and methods of fabrication
First Claim
1. An apparatus comprising:
- a neutron-detecting structure, the neutron-detecting structure comprising;
a substrate comprising a plurality of cavities extending into the substrate from a surface thereof;
a p-n junction within the substrate and extending, at least in part, in spaced opposing relation to inner cavity walls of the substrate defining the plurality of cavities therein;
a neutron-responsive material disposed within the plurality of cavities, the neutron-responsive material being responsive to neutrons absorbed thereby for releasing ionizing radiation reaction products, wherein the p-n junction within the substrate spaced in opposing relation to and extending, at least in part, along the inner cavity walls of the substrate reduces leakage current of the neutron-detecting structure;
wherein the p-n junction within the substrate is a continuous p-n junction, the continuous p-n junction being disposed, in part, parallel to the surface of the substrate from which the plurality of cavities extend into the substrate, as well as in spaced opposing relation to the inner cavity walls of the substrate; and
wherein the continuous p-n junction is spaced from the surface of the substrate a greater distance than the continuous p-n junction is spaced in opposing relation to the inner cavity walls of the substrate.

Abstract
Neutron-detecting structures and methods of fabrication are provided which include: a substrate with a plurality of cavities extending into the substrate from a surface; a p-n junction within the substrate and extending, at least in part, in spaced opposing relation to inner cavity walls of the substrate defining the plurality of cavities; and a neutron-responsive material disposed within the plurality of cavities. The neutron-responsive material is responsive to neutrons absorbed for releasing ionization radiation products, and the p-n junction within the substrate spaced in opposing relation to and extending, at least in part, along the inner cavity walls of the substrate reduces leakage current of the neutron-detecting structure.
