Photoluminescent and gas-sensing properties of ZnO nanowires prepared by an ionic liquid assisted vapor transfer approach
Kittitat Subannajui,Chatchawal Wongchoosuk,Niranjan S. Ramgir,Chunyu Wang,Yang Yang,A. M. Hartel,Volker Cimalla,Margit Zacharias +7 more
TL;DR: In this paper, the ionic liquid assisted technique was used to control the growth characteristic of ZnO nanowires (NWs), which was shifted from polar c-to non-polar a-orientation.

Electron tunneling from colloidal CdSe quantum dots to ZnO nanowires studied by time-resolved luminescence and photoconductivity experiments
Stephanie Bley,Michael Diez,Friederike Albrecht,Sebastian Resch,Siegfried R. Waldvogel,Andreas Menzel,Margit Zacharias,Jürgen Gutowski,Tobias Voss +8 more
TL;DR: CdSe quantum dots with different organic linker molecules are attached to ZnO nanowires (NWs) to study the luminescence dynamics and the electron tunneling from the QDs to the NNs in time-resolved photoluminescence (PL) and photoconductivity measurements as mentioned in this paper.
Journal ArticleDOI
Toward Discrete Multilayered Composite Structures: Do Hollow Networks Form in a Polycrystalline Infinite Nanoplane by the Kirkendall Effect?
Firat Güder,Yang Yang,Silvana Goetze,Andreas Berger,Roland Scholz,Daniel Hiller,Dietrich Hesse,Margit Zacharias +7 more
TL;DR: In this article, a multilayered system consisting of alternating layers of ZnO and Al2O3 grown by atomic layer deposition (ALD) was used to investigate the effects of annealing temperature, annealling duration, layer thickness, polycrystallinity, grain size, and reaction space on the solid-state diffusion process and final morphology of the produced Kirkendall voids.
Journal ArticleDOI
Ultra-long zinc oxide nanowires and boron doping based on ionic liquid assisted thermal chemical vapor deposition growth
Andreas Menzel,Kris Komin,Yang Yang,Firat Güder,Vanessa Trouillet,Peter Werner,Margit Zacharias +6 more
TL;DR: It is found that decomposed components of the ionic liquid at higher temperatures facilitate ultra-long vapor-liquid-solid ZnO nanowires that exhibit an unusual a-axis orientation.
