Abstract

A buffer structure (1) comprising a compositionally graded layer of a nitride alloy (5) comprising two or more Group IIIB elements, for example La, Y, Sc or Ac, is used to modify a silicon substrate (3) to produce a universal substrate on which a range of target materials (7), for example GaN, may be deposited to produce semiconductor devices for electronic and optical applications. The resulting lattice parameter L varies with thickness T through the structure.
