Transmission electron microscopy study of an electron-beam-induced phase transformation of niobium nitride
Tetragonal γ-NbN 1 − x was irradiated with 300 keV electrons at room temperature to fluences from 1.8 × 10 24–5.4 × 10 26 e/m 2. The superlattice structure in γ-NbN 1 − x was observed using transmission electron microscopy and found to disappear at a fluence of 5.4 × 10 26 e/m 2. During this process...
