We have carried out an investigation on nanostructure evolution of GaAs(100) surface due to normal incidence of threshold energy ion irradiation at different elevated temperatures. Well-ordered ripple nanopatterns are observed above 350°C near to surface recrystallization temperature where ripple wave-vector is oriented along 110 crystallographic d...

... correlation length is basically the extent up to which the lateral correlation of the system exists and defines by the width of the auto-correlation function at which , being the base of natural logarithm [16] corresponds to different temperatures are extracted from the corresponding AFM images and are shown by figure 4. The correlation lengths for different temperatures are calculated from the corresponding curves displayed in figure 4(a) and are represented by figure 4(b) which again shows an increase of correlation length after substrate temperature 300C. ...
