A solid state ionizing radiation detector is provided, having an absorber within which, when in use, electrical charge is generated upon the absorption of ionizing radiation. The absorber has a front face with an active region through which incident ionizing radiation is received. A front electrode is located at the front face. A rear electrode substantially covers a rear face of the absorber. The front and rear electrodes are arranged in use to generate an electric field in the absorber so as to collect the generated electrical charge. The area of the rear face is substantially smaller than that of the active region of the front face. At least part of the absorber within which the electric field is generated is bounded by substantially smooth and substantially tapered sidewalls.
