Abstract

The spatial scaling law and intermittency of the V2O5V_2 O_5 surface roughness by atomic force microscopy has been investigated. The intermittency of the height fluctuations has been checked by two different methods, first, by measuring scaling exponent of q-th moment of height-difference fluctuations i.e. Cq=<h(x1)h(x2)q>C_q = < |h(x_1) - h(x_2)|^{q} > and the second, by defining generating function Z(q,N)Z(q,N) and generalized multi-fractal dimension DqD_q. These methods predict that there is no intermittency in the height fluctuations. The observed roughness and dynamical exponents can be explained by the numerical simulation on the basis of forced Kuramoto-Sivashinsky equation.
