Planarized arrays of aligned, untangled multiwall carbon nanotubes with Ohmic back contacts

Autor: Steven J. Limmer, Michael P. Siegal, S. W. Howell, Caitlin Rochford, Thomas E. Beechem

Publikováno v: Journal of Materials Research. 30:315-322

Vertically aligned, untangled planarized arrays of multiwall carbon nanotubes (MWNTs) with Ohmic back contacts were grown in nanopore templates on arbitrary substrates. The templates were prepared by sputter depositing Nd-doped Al films onto W-coated

An investigation of weld fracture surfaces and mechanical properties of two gamma titanium aluminide alloys

Autor: S. W. Howell, V. L. Acoff

Publikováno v: Practical Failure Analysis. 3:63-73

Two gamma titanium aluminide sheet materials were investigated to characterize the fusion zone cracking and mechanical properties that occur for specimens subjected to gas tungsten arc welding (GTAW). The materials used in this study consisted of ess

Time evolution studies of the electrostatic surface potential of low-temperature-grown GaAs using electrostatic force microscopy

Autor: S. W. Howell, D. B. Janes

Publikováno v: Journal of Applied Physics. 97:043703

An electrostatic force microscope was used to measure the electrostatic surface potential of low-temperature-grown GaAs (LTG:GaAs) before and after the removal of the native oxide layer. The surface potential of oxidized LTG:GaAs was found to be 450�
