Nano-quasicrystalline particles in Mn-ion mplanted GaAs

摘要

Both icosahedral and decagonal quasicrystalline particles of a few tens of nanometers in size have been found in Mn-ion implanted GaAs single rystals with a dose of 8x10~16 Mn+/cm~2 by high resolution electron microscopy (HREM).The identity of these qasicrystals was confirmed by the Fourier transofrms made from these HREM images and their composition measured by micro-probe X-ray analysis and electron energy loss spectroscopy was 38-45 at.
