Patent ID: 7199015

Claim:
A method of deposition of semiconductors, comprising: providing a substrate; epitaxially depositing on the substrate a composition selected from at least one of: (1) a rare-earth oxide of the formula: [RE] x [O] y , where x and y are real positive numbers less than or equal to 3, RE is at least one type of rare-earth metal atom; (2) a binary single-crystal rare-earth nitride of the formula: RE x N y where x and y are real positive numbers less than or equal to 2, RE is at least one type of rare-earth metal atom; (3) a binary single-crystal rare-earth phosphide of the formula: RE x P y where x and y are real positive numbers less than or equal to 2, RE is at least one rare-earth metal atom; (4) a rare-earth oxy-nitride ternary of the formula: [RE] x [O 1-z N z ] y , where x and y are real positive numbers less than 3 and z is greater or equal to zero and less than equal to 1, RE is at least one type of rare-earth metal atom; (5) a silicon rare-earth oxide, nitride, phosphide ternary or quaternary alloy of the formula: [(RE) x (O or N or P) y ][Si or Ge or SiGe] z , where x, y and z are real positive numbers less than or equal to 5, RE is at least one rare-earth metal; (6) a ternary alloy of a non rare-earth atom with either rare-earth oxide, rare-earth nitride or rare-earth phosphide of the formula: [(RE) x (O or N or P) y ][M] z , where RE is at least one type of rare-earth metal, M is a non-rare-earth, x, y and z individually take values ranging from real positive number less than or equal to 5; and wherein a majority of the composition is single crystal.
