An amorphizing implant is performed using a high dose of arsenic (5 x 105 cm-2, 200 keV) and TEM cross-section images indicate complete amorphization to a depth of 50 nm.
If Solid-Phase Epitaxial (SPE) regrowth instantly removes all of the damage in the amorphous region, calculate the fraction of the "+1" implanted dose that is available for TED.
