Abstract:
1. An apparatus comprising: a first semiconductor layer, wherein the first semiconductor layer is substantially non-conducting and is substantially undoped, the first semiconductor layer having a first side and a second side; a sensing layer located under the first semiconductor layer, the sensing layer comprising a layer of semiconductor material having a Boron 10 p-type dopant wherein the sensing layer is configured to react when neutrons move into the sensing layer; a second semiconductor layer located under the sensing layer, wherein the second semiconductor layer is substantially non-conducting and is substantially undoped, the second semiconductor layer having a first side and a second side; a first conductive layer located on the second side the first semiconductor layer; and a second conductive layer located on the second side of the second semiconductor layer, wherein the sensing layer is located on the first side of the first semiconductor layer and the first side of the second semiconductor layer, and wherein the sensing layer is configured such that a neutron captured in the boron 10 sensing layer generates a helium 4 and a lithium 7 nuclei that scatter into the first semiconductor layer and the second semiconductor layer.
