On the rotational alignment of graphene domains grown on Ge(110) and Ge(111)
P. C. Rogge, M. E. Foster, J. M. Wofford +3
We have used low-energy electron diffraction and microscopy to compare the growth of graphene on hydrogen-free Ge(111) and Ge(110) from an atomic carbon flux. Growth on Ge(110) lea…
Synthesis of atomically thin hexagonal boron nitride films on nickel foils by molecular beam epitaxy
S. Nakhaie, J. M. Wofford, T. Schumann +5
Hexagonal boron nitride (h-BN) is a layered two-dimensional material with properties that make it promising as a dielectric in various applications. We report the growth of h-BN fi…
Influence of lattice orientation on growth and structure of graphene on Cu(001)
Joseph M. Wofford, Shu Nie, Konrad Thürmer +2
We have used low-energy electron microscopy and diffraction to examine the significance of lattice orientation in graphene growth on Cu(001). Individual graphene domains undergo an…
Graphene/Au(111) interaction studied by scanning tunneling microscopy
Shu Nie, Norman C. Bartelt, Joseph M. Wofford +3
We have used scanning tunneling microscopy to study the structure of graphene islands on Au(111) grown by deposition of elemental carbon at 950°C. Consistent with low-energy electr…
Extraordinary epitaxial alignment of graphene islands on Au(111)
Joseph M. Wofford, Elena Starodub, Andrew L. Walter +7
Pristine, single-crystalline graphene displays a unique collection of remarkable electronic properties that arise from its two-dimensional, honeycomb structure. Using in-situ low-e…
Origin of the Mosaicity in Graphene Grown on Cu(111)
S. Nie, J. M. Wofford, N. C. Bartelt +2
We use low-energy electron microscopy to investigate how graphene grows on Cu(111). Graphene islands first nucleate at substrate defects such as step bunches and impurities. A cons…
