Patent ID: 10892294

Abstract:
The invention relates to a radiation detector element (10) comprising a stack (15) of layers superimposed in a stacking direction (Z), the stack (15) having a first face (25) and a second face (30) and comprising a radiation-absorbing layer (35) consisting of a first semiconductor material (M1) having a first band gap value and at least one barrier layer (40) consisting of a second semiconductor material (M2) having a second band gap value, the second band gap value being strictly higher than the first band gap value. The second face (30) has at least one strip (105) defined in the stacking direction (Z) by the barrier layer (40), the strip (105) consisting of the second semiconductor material (M2) and having a doping of the first type and a free carrier density higher than or equal to 1.1017 cm−3.
