Abstract
Radiation damage tests in hydrogenated amorphoussilicon (a-Si:H) flexible flux and dose-measuring devices havebeen performed with a 3-MeV proton beam, to evaluate combineddisplacement and total ionizing dose damage. The tested deviceshad two different configurations and thicknesses. The first devicewas a 2-μm-thick n-i-p diode having a 5 × 5 mm area. Thesecond device was a 5-μm-thick charge-selective contact (CSC)detector having the same area. Both the devices were depositedon a flexible polyimide substrate and were irradiated up to thefluence of 1016 neq/cm2. The response to different proton fluxeshas been measured before irradiation and after irradiation at1016 neq/cm2 for CSCs and n-i-p devices. The effect of annealingfor partial performance recovery at 100 ◦C for 12 h was alsostudied, and a final characterization on annealed devices wasperformed. This test is the first combined displacement and totalionizing dose test on flexible a-Si:H devices.
