(a) A multichannel semiconductor X-ray detector along with the diffusing charges from an X-ray absorption point in the field-free substrate. X-rays are injected at x = y = 0. (b) The dashed, dot-dashed, solid and dotted curves represent the diffusion signals Jsx(y) calculated from our three-dimensional diffusion theory [see equation (6)] for a unit-intensity X-ray at 5 keV using L = 50, 75, 100 and 150 µm, respectively. |
