Each of the plurality of grooves includes a first sidewall that is coplanar with a second crystallographic plane and a second sidewall that is coplanar with a third crystallographic plane. A buffer layer is provided on the substrate to reduce mechanical strain between the substrate and a light emitting diode (LED) fabricated on the buffer layer.
