Show transcribed data Silver bromide (AgBr) has rock salt crystal structure, i.e., FCC Bravais lattice with the ion pair, Ag+ and Br- as basis. The dominant defect in AgBr is the Frenkel disorder

A) Does the Frenkel disorder in AgBr create vacancies of Ag+, vacancies of Br-, or both? Explain

B) If is 1.16eV per hole with entropic factor A=3.091, calculate the temperature at which the hole concentration fraction becomes 1 ppb
