Consider a two-dimensional ionic crystal with a primitive hexagonal lattice. The energy needed to create a Frenkel defect pair is 10eV, and Schottky defect formation costs 8eV. Calculate the concentration of vacancies and interstitials in the crystal at 300 K, assuming that all defects are intrinsic. n/N=e-(Edef/kbT) Where: n = number of defects N = number of atoms in the crystal Edef = defect creation energy kb = Boltzman's constant T = temperature I've tried using 10eV and 8eV as the defect creation energy however this equals to an answer smaller than *10-100, unsure how to progress. Thanks in advance!
