Abstract
Examples of device structures utilizing layers of rare earth oxides to perform the tasks of strain engineering in transitioning between semiconductor layers of different composition and/or lattice orientation and size are given. A structure comprising a plurality of semiconductor layers separated by transition layer(s) comprising two or more rare earth compounds operable as a sink for structural defects is disclosed.
