Journal ArticleDOI
Growth of Highly Doped P-Type Znte Films by Pulsed Laser ablation in Molecular Nitrogen
Douglas H. Lowndes,Christopher M. Rouleau,James W. McCamy,John D. Budai,David B. Poker,David B. Geohegan,Alexander A. Puretzky,Shen Zhu,Shen Zhu +8 more
TL;DR: In this article, high-purity ZnTe films were grown on semi-insulating GaAs (001) substrates by pulsed-laser ablation (PLA) of a stoichiometric target in a highpurity N{sub 2} ambient without the use of any assisting (DC or AC) plasma source.
Proceedings ArticleDOI
Pulsed-laser-deposited amorphous diamond and related materials: synthesis, characterization, and field emission properties
Vladimir I. Merkulov,Douglas H. Lowndes,Larry R. Baylor,Gerald Earle Jellison Jr,Alexander A. Puretzky,David B. Geohegan +5 more
TL;DR: In this paper, an in-situ ion probe was used to measure kinetic energy of C{sup +} ions, with the advantage of being readily transferable for inter-laboratory comparisons.
Proceedings ArticleDOI
Crystallinities and Light Emitting Properties of Nanostructured SiGe Alloy Prepared by Pulsed Laser Ablation in Inert Background Gases
Takehito Yoshida,Yuka Yamada,Nobuyasu Suzuki,Toshiharu Makino,Takaaki Orii,Kouichi Murakami,David B. Geohegan,Douglas H. Lowndes,Michael J. Aziz +8 more
TL;DR: In this article, a pulsed laser ablation method was used to study the material properties of nanostructured group IV materials, where an ArF excimer laser was focused onto the surface of the powder-sintered SixGe1-x target.

Apparatus for controlled alignment of catalytically grown nanostructures
Vladimir I. Merkulov,Anatoli V. Melechko,Michael A. Guillorn,Douglas H. Lowndes,Michael L. Simpson +4 more
TL;DR: In this article, a system for controlled alignment of catalyticaly grown nanostructures in a large-scale synthesis process is described, which includes an electrode including a protruding section defining an edge; and a nonprotruding section coupled to the protruding area, where the edge is adapted to deflect an electric field generated with the electrode.
Book ChapterDOI
Kosterlitz-Thouless-Like Behavior Over Extended Ranges of Temperature and Layer Thickness in Crystalline YBa2Cu3O7-x/PrBa2Cu3O7-x Superlattices
TL;DR: In this paper, the superconductivity of single-cell-thick layers of the YBa2Cu3O7-x (YBCO) family was investigated and the superlattice Tco(R = 0) was found to decrease rapidly with increasing PBCO layer thickness.
