ABSTRACT:
A composite material that may be used for a thin membrane is disclosed. This composite material includes first material that has a quasi-periodic system of vertical trenches (nanotrenches) with wavelength period that may be in the range between 20 and 500 nm. These nanotrenches are formed as openings between bordering elongated elements. The nanotrenches are at least partially filled with a second material that has physical-chemical characteristics substantially different from the first material.
