Description

We report the first results on irradiated 3D Double Side Double Column devices using Three-Photon and Two-Photon Absorption Transient Current Technique. Devices are fabricated at the CNM in Barcelona (3D Rd50 Project) and irradiated at the Josef Stefan Institute at two fluences: 10^15 and 10*17 neq/cm2. Multicell 3D Hex structure was studied. Additionally, we show the results from the Single Photon Absorption - TCT where several wavelengths were exploited. This study is performed on the same sample on which 2PA and 3PA- TCT were performed. For comparison and as reference data, we show also results from SPA, 2PA and 3PA on non-irradiated 3D Hex structure.
