“…TID is considered a severe problem (Claeys and Simoen 2002) during the lifetime of satellites. Displacement Damage Dose (DDD) or "Bulk" damage ( Barth et al 2004;Yu et al 2005), occurs when high energy particles dislodge or displace atoms from the semiconductor lattice due to its long time exposure to non ionising energy loss (NIEL). DDD results in a similar long-term cumulative degradation to that caused by TID.…”
