This paper describes an engineering method for nucleating nanocrystalline carbon films on monocrystalline silicon using a combination of microwave and radio frequency plasma-assisted chemical vapor deposition. The approach is demonstrated via deposition of nanocrystalline diamond after a seeding step and growth of…

This experimental study examined nucleation of superconductivity at the surface of a single-crystal yttrium hexaboride (YB6) in a tilted dc magnetic field. The authors measured Hc3 on each side of the sample as a function of the angle between the field and the surface. They report Hc3/Hc2 ≈ 1.28 for a perpendicular…
