In a Schottky defect, what is missing from the lattice?
AEqual numbers of cations and anions
BOnly the cations from the lattice
COnly the anions from the lattice
DAn ion shifted to an interstitial site
Answer & Solution
Correct answer: A. Equal numbers of cations and anions
A Schottky defect is a paired cation-anion vacancy, so electrical neutrality is kept.
