increasing their sensitivity to displacement damage from electrons and protons. Although displacement damage effects can be easily treated for individual transistors [2,3], the net effect on linear circuits can be far more complex because circuit operation often depends on the interaction of several internal transistors.

The testing of displacement damage is usually done with either protons or neutrons. Fraunhofer INT offers two neutron generators (Fig. 1) which are suitable for investigating displacement-damage effects in electronic or optical …
Often the energy of the incoming particle is high enough to displace several atoms and the displaced atoms themselves can displace other atoms on their way ...
Bulk displacement damage effects are seen to dominate the radiation response in state of ... It is based on the concept of non-ionising energy loss (NIEL), ...
Displacement Damage is the result of nuclear interactions, typically scattering, which cause lattice defects. Displacement damage degrades minority carrier lifetime; a typical effect would be degradation of gain and leakage current in bipolar transistors. Atomic displacement can occur mainly ballistically through kinetic energy transfer.
01.08.2014 · We developed a simple method to prepare the displacement damage cross section of SiC using NJOY and SRIM/TRIM. The number of displacements per atom (DPA) dependent on primary knock-on atom (PKA) energy was computed using SRIM/TRIM and it is directly used by NJOY/HEATR to compute the neutron energy dependent DPA cross sections which are …
The cumulative damage of the semiconductor lattice ( lattice displacement damage) caused by ionizing radiation over the exposition time. It is measured in rads and causes slow gradual degradation of the device's performance.
This displacement damage creates defect energy levels in semiconductors that can act as trapping and recombination centers. It is the introduction of these defect levels that degrade the photovoltaic response of a solar cell through a reduction in the minority carrier diffusion length.
In the case of displacement damage, the energy deposition process is determined by the nonionizing energy loss (NIEL), instead of linear energy transfer ...
