Query: Many-body theory for proton-induced point-defect effects on losses of
  electron energy and photons in quantum wells   The effects of point defects on the loss of either energies of ballistic
electron beams or incident photons are studied by using a many-body theory in a
multi-quantum-well system. This includes the defect-induced vertex correction
to a bare polarization function of electrons within the ladder approximation as
well as the intralayer and interlayer screening of defect-electron interactions
are also taken into account in the random-phase approximation. The numerical
results of defect effects on both energy-loss and optical-absorption spectra
are presented and analyzed for various defect densities, number of quantum
wells, and wave vectors. The diffusion-reaction equation is employed for
calculating distributions of point defects in a layered structure. For
completeness, the production rate for Frenkel-pair defects and their initial
concentration are obtained based on atomic-level molecular-dynamics
simulations. By combining defect-effect, diffusion-reaction and
molecular-dynamics models proposed in this paper with a space-weather forecast
model for the first time, it will be possible to enable specific designing for
electronic and optoelectronic quantum devices that will be operated in space
with radiation-hardening protection, and therefore, will effectively extend the
lifetime of these satellite onboard electronic and optoelectronic devices.
