Journal ArticleDOI
High electron mobility of epitaxial ZnO thin films on c-plane sapphire grown by multistep pulsed-laser deposition
E. M. Kaidashev,Michael Lorenz,H. von Wenckstern,Andreas Rahm,H.-C. Semmelhack,K.-H. Han,Gabriele Benndorf,Carsten Bundesmann,Holger Hochmuth,Marius Grundmann +9 more
TL;DR: In this article, a multistep pulsed-laser deposition (PLD) process is presented for epitaxial, nominally undoped ZnO thin films of total thickness of 1 to 2 μm on c-plane sapphire substrates.
Journal ArticleDOI
Room temperature ferromagnetism in ZnO films due to defects
Qingyu Xu,Heidemarie Schmidt,Shengqiang Zhou,Kay Potzger,Manfred Helm,Holger Hochmuth,Michael Lorenz,Annette Setzer,Pablo Esquinazi,Christoph Meinecke,Marius Grundmann +10 more
TL;DR: In this article, the anomalous Hall effect (AHE) was observed in ferromagnetic ZnO as well as in nonferromagnetic Cu-doped ZnOs, indicating that AHE does not uniquely prove ferromagnetism.
Journal ArticleDOI
Defect-induced magnetic order in pure ZnO films
M. Khalid,Michael Ziese,Annette Setzer,Pablo Esquinazi,Michael Lorenz,Holger Hochmuth,Marius Grundmann,Daniel Spemann,Tilman Butz,G. Brauer,W. Anwand,G. Fischer,Waheed A. Adeagbo,Wolfram Hergert,Arthur Ernst +14 more
TL;DR: In this paper, the magnetic properties of pure ZnO thin films were investigated by pulsed-laser deposition on a variety of substrates and they showed reproducible ferromagnetism at 300 K when grown at $300--400\text{ }\ifmmode^\circ\else\textdegree\fi{}\text{C}$ and 0.1--1.0 mbar
Journal ArticleDOI
MgxZn1−xO(0⩽x<0.2) nanowire arrays on sapphire grown by high-pressure pulsed-laser deposition
Michael Lorenz,E. M. Kaidashev,Andreas Rahm,Th. Nobis,Jörg Lenzner,Gerald Wagner,Daniel Spemann,Holger Hochmuth,Marius Grundmann +8 more
TL;DR: In this paper, high-pressure pulsed-laser deposition (PLD) was used to grow MgxZn1−xO nanowires on gold-covered sapphire single crystals.
Journal ArticleDOI
Room temperature ferromagnetism in carbon-implanted ZnO
Shengqiang Zhou,Qingyu Xu,Kay Potzger,G. Talut,R. Grötzschel,Jürgen Fassbender,Mykola Vinnichenko,Jörg Grenzer,Manfred Helm,Holger Hochmuth,Michael Lorenz,Marius Grundmann,Heidemarie Schmidt +12 more
TL;DR: Pan et al. as discussed by the authors introduced carbon into ZnO films by ion implantation, and room temperature ferromagnetism has been observed. But the results were limited to the case of C-doped ferromagnetic ZnOs.
