Relative stability of quasicrystals and Frank-Kasper phases of similar composition
Fradkin M. A.
The electron component of the energy of quasicrystals and of crystalline phases of approximately the same composition, whose structure is described by a rational cross section of a six-dimensional space, is analyzed in the approximation of nearly free electrons. The mechanism proposed here can explain the stability of such phases in the Al-Li-Cu system.
