Spectral dependence of the photocurrent measured for p- and s-polarized light at normal incidence for two types of metal film correlation in surface-barrier heterosrtuctures based on Schottky barrier with geometrical parameters: a quasi-anticorrelated relief L=750 nm, h=50 nm, h _{Au 1}=20 nm, and h _{Au 2}=35 nm and b correlated (sinusoidal) relief L=760 nm, h=70 nm, and h _Au =40 nm. The schematic cross section of structure with quasi-anticorrelated metal film interfaces is presented in Fig. 2
