Abstract
Perfect crystals constitute an idealization of real single crystals that always contain some crystal defects. This holds even for almost perfect single crystals, so-called whiskers, where the presence of an equilibrium concentration of vacancies is inevitable. On the other hand, the mechanical behaviour of perfect crystals can be very successfully simulated and predicted by theoretical ab initio approaches based on electronic structure calculations. Because many of the crystallographic, elastic, electric, magnetic and thermodynamic characteristics of crystals do not depend on crystal defects, the ab initio results can still be experimentally verified. The practical importance of such studies lies in several general aspects.
