Abstract
Compound semiconductor and silicon-based structures are epitaxially formed on semiconductor substrates and transferred to a carrier substrate. The transferred structures can be used to form discrete photovoltaic and light-emitting devices on the carrier substrate. Silicon-containing layers grown on doped donor semiconductor substrates and compound semiconductor layers grown on off-cut semiconductor substrates form elements of the devices. The carrier substrates may be electrically insulating substrates or include electrically insulating layers to which photovoltaic and/or light-emitting structures are bonded.
