41. Preparation and Certification of Hydrogen in Titanium Alloy Standard Reference Materials
Topic: Materials Science
Published: 8/4/2012
Authors: Rick L Paul, Richard Mark Lindstrom
Abstract: A series of three Hydrogen in Titanium Alloy Standard Reference Materials (SRMs 2452, 2453, and 2454) were prepared with hydrogen mass fractions bracketing the hydrogen specification limit of 125 mg/kg. Commercial titanium alloy Ti6Al4V (6 % alu ...

42. Determination of graphene work function and graphene-insulator-semiconductor band alignment by internal photoemission spectroscopy
Topic: Materials Science
Published: 7/11/2012
Authors: Rusen Yan, Qin Zhang, Wei Li, Irene G. Calizo, Tian T. Shen, Curt A Richter, Angela R Hight Walker, Xuelei X. Liang, David J Gundlach, Nhan V Nguyen, Huili Grace Xing, Alan Seabaugh
Abstract: We determined the band alignment of a graphene-oxide-silicon structure using internal photoemission spectroscopy. From the flatband voltage and Dirac voltage we infer a 4.3  10e11 cm-2 negative extrinsic charge present on the graphene surface. Als ...
