Iron nanoparticles were produced by the evaporation method and their average sizes are estimated 25,50, 90 and 120 nm using the laser particle analyzer. Assuming that the resultant particles are strain freeand the peak broadening detected in the measurement with Cu-K radiation (λ=0.154 nm) arises onlyfrom variation of size of the crystallites, estimate the peak width (the value of FWHM) of the (110) plane.
A Raman spectrum of undoped GaAs at room temperature is performed with a 514.5 nm laser.
