Web10,14). Epitaxially biphenyl is known to be sensitive to the surface morphology of the underlayer and the conformer of biphenyl as an overlayer will vary, depending on the nature of this underlayer (15). In a companion study to this one (16), the planar conformer of biphenyl was found to be formed by deposition on Al 2 O 3 by Biphenyl (also known as diphenyl, phenylbenzene, 1,1′-biphenyl, lemonene or BP) is an organic compound that forms colorless crystals.
