Scale-dependent roughening kinetics in vapor deposited gold

The roughening kinetics of gold deposits grown from vapor was studied by scanning tunneling microscopy. The dynamic scaling yielded the following growth exponents α(I)=0.90±0.06 and β(I)=0.25±0.06 for L<sub>s</sub>>d<sub>s</sub>, and α(II)=0.37±0.05 and β(II)=0.45±0.06 for...

Sumario:The roughening kinetics of gold deposits grown from vapor was studied by scanning tunneling microscopy. The dynamic scaling yielded the following growth exponents α(I)=0.90±0.06 and β(I)=0.25±0.06 for L<sub>s</sub>>d<sub>s</sub>, and α(II)=0.37±0.05 and β(II)=0.45±0.06 for L<sub>s</sub>>d<sub>s</sub>, where L<sub>s</sub> is the scan length and d<sub>s</sub> is the average diameter of columns. The scaling properties of the domain-dependent-surface roughness exponents allowed us to give the rationale for experimental data on the fractal behavior of thin metal films.
