Scientific Objectives

  • Increase the understanding of nucleation and growth conditions for MAN-phases, in particular Ti2AlN and Ti4AlN3.
  • Try out conditions for forming a new Ti3AlN2-phase
  • Make the first MAN films containing Ga, In or Sc.
  • Identify phase composition and properties of nanocomposite films of corresponding (N-deficient) composition.

Technology Transfer Objectives

  • Show the feasibility of using MAN-phases as ohmic contacts to wide-band-gap epilayers of AlN or GaN

Research plan:

  • Use in situ X-ray Reflectivity measurements to characterize the conditions for nucleation and growth of 211, 312, and 413 type of MAN-phases during reactive magnetron sputtering of Ti and Al.
  • Reactive magnetron sputtering calculations to identify ternary systems with a large miscibility gap.
  • Deposit Ti2AlN films by cathodic arc deposition
