Abstract
Selected micro- and nanoscale, 1-dimensional and 2-dimensional periodic and random structures generated on silicon and other substrates are expected to perform as compliant, thin films for gettering defects and for accommodating lattice and thermal expansion mismatches during heteroepitaxial growth thereon, thereby leading to relatively defect-free, heteroepitaxial films of chosen thicknesses. The as-grown epilayers or completed electronic and optoelectronic devices can be bonded to a second substrate such as glass, or plastic following separation thereof from the substrate on which they were formed using preferential etching of a readily detachable, nanoporous silicon or silicon dioxide layer introduced between the generated structures and the substrate.
