Journal ArticleDOI
Emission of coherent THz radiation from superconductors.
Lutfi Ozyuzer,Alexei Koshelev,Cihan Kurter,Cihan Kurter,Nachappa Gopalsami,Qiang Li,Masashi Tachiki,Kazuo Kadowaki,Takashi Yamamoto,Hidetoshi Minami,Hiroshi Yamaguchi,Takashi Tachiki,Kenneth E. Gray,Wai-Kwong Kwok,Ulrich Welp +14 more
TL;DR: In this article, the authors demonstrate that coherent continuous-wave terahertz (THz) radiation of sizable power can be extracted from intrinsic Josephson junctions in the layered high-temperature superconductor Bi 2 Sr 2 CaCu 2 O 8.
Journal ArticleDOI
Organic superconductors--new benchmarks.
Jack M. Williams,Arthur J. Schultz,Urs Geiser,K. Douglas Carlson,Aravinda M. Kini,Hsien-Hau Wang,Wai-Kwong Kwok,Myung-Hwan Whangbo,J. E. Schirber +8 more
TL;DR: The largest number of organic superconductors, including those with the highest Tc values, are charge-transfer salts derived from the electron donor molecule BEDT-TTF or ET [bis(ethylenedithio)-tetrathiafulvalene].
Journal ArticleDOI
Self-assembled monolayer-enhanced hydrogen sensing with ultrathin palladium films
TL;DR: In this paper, a siloxane self-assembled monolayer placed between a substrate and an evaporated ultrathin Pd film promotes the formation of small Pd nanoclusters and reduces the stiction between the palladium and the substrate.
Journal ArticleDOI
Calorimetric measurement of the latent heat of vortex-lattice melting in untwinned YBa 2 Cu 3 O 7-δ
Andreas Schilling,R. A. Fisher,N. E. Phillips,Ulrich Welp,D. Dasgupta,Wai-Kwong Kwok,G. W. Crabtree +6 more
TL;DR: In this paper, a calorimetric measurement of a latent heat provided the most definitive proof of the occurrence of a first-order transition at a well defined phase boundary at the upper critical field Hm(T).
Journal ArticleDOI
Fabrication of Alumina Nanotubes and Nanowires by Etching Porous Alumina Membranes
Zhili Xiao,Catherine Y. Han,Ulrich Welp,Hsien-Hau Wang,Wai-Kwong Kwok,Gerold A. Willing,Jon Hiller,R. E. Cook,Dean J. Miller,G. W. Crabtree +9 more
TL;DR: In this paper, a high yield of alumina nanotubes/nanowires is obtained by etching porous alumina membranes in an aqueous sodium hydroxide solution.
