Abstract
Low strain heteroepitaxy of (111) silicon on (111) lithium aluminum between the reconstructed 7.times.7 surface of (111) silicon and a 6.times.6 array of aluminum atoms on the surface of the (111) lithium aluminum. The 7.times.7 reconstructed (111) silicon surface contains 36 silicon atoms and 13 vacancies for every 49 surface sites. The 36 silicon atoms on an area averaged basis match the 36 aluminum atoms in the 6.times.6 aluminum diamond structure (zero vacancies) present at the (111) surface of lithium aluminum to within about 1%.
