Investigation on buffer layer for InN growth by molecular beam epitaxy

Growth of InN on Ge substrate by molecular beam epitaxy

InN epitaxial growth on a (1 1 1)-oriented, Ga-doped germanium substrate using molecular beam epitaxy is described. X-ray diffraction and transmission electron microscopy investigations have shown that the InN epitaxial layer consists of a wurtzite structure, which has the epitaxial relationship of (0 0 0 1)InNJ(1 1 1)Ge. Transmission electron microscopy shows an intermediate layer at the inter...

Title Growth mode and strain evolution during InN growth on GaN(0001) by molecular-beam epitaxy

Direct graphene growth on Co3O4(111) by molecular beam epitaxy.

Direct growth of graphene on Co(3)O(4)(111) at 1000 K was achieved by molecular beam epitaxy from a graphite source. Auger spectroscopy shows a characteristic sp(2) carbon lineshape, at average carbon coverages from 0.4 to 3 ML. Low energy electron diffraction (LEED) indicates (111) ordering of the sp(2) carbon film with a lattice constant of 2.5(±0.1) Å characteristic of graphene. Sixfold symm...

Growth of GaN on porous SiC by molecular beam epitaxy

Growth of GaN on SiC(0001) by Molecular Beam Epitaxy

GaN films are grown by plasma-assisted molecular beam epitaxy on 6H-SiC(0001) substrates. Suitable substrate preparation and growth conditions are found which greatly improve the structural quality of the films. Threading dislocation densities of about 1 10 cm for edge dislocations and 1 10 cm for screw dislocations are achieved in GaN films of 1 m thickness grown under optimal conditions. Reve...
