Hand-held instruments that can be used to passively detect and identify sources of neutron radiation—either bare or obscured by neutron moderating and/or absorbing material(s)—in real time are of interest in a variety of nuclear non-proliferation

Semiconductor diode detectors coated with neutron reactive materials are generally fashioned as planar diodes coated with 10B, 6LiF, or Gd. Planar detectors coated with 10B or 6LiF are limited to less than 5% intrinsic thermal neutron detection effic

The design of an idealized perforated (microstructured) planar diode neutron detector is presented that has little variation in efficiency as a function of the incident neutron's direction. The reduced angular variation is obtained by using sinusoida
