Abstract: A quasicrystalline material and a semiconductor device to which the quasicrystalline material is applied are disclosed. A quasicrystalline material is based on a quasicrystalline element having one or more axis of symmetry (e.g., a 2-fold axis, a 3-fold axis, a 5-fold axis, or a higher fold axes of symmetry). The quasicrystalline material is capable of phase changes between a quasicrystalline phase and an approximant crystalline phase having a further regular atom arrangement than the quasicrystalline phase. The quasicrystalline material that may be used as a phase change material and may be applied to a phase change layer of a semiconductor device.
