Laminated semiconductor radiation detector

A detection system which includes at least one element enabling the detection of high-energy radiation. The element has a multilayered structure including a lower electrode, a first layer including a semiconducting dark current effects reducing substance deposited on the lower electrode, a second layer including a wide band gap semiconducting substance deposited onto the first layer, and an upper electrode deposited onto the second layer. In other embodiments, the positioning of the first and second layers is reversed.
