    • Controlling spin current polarization through non-collinear antiferromagnetism 

      Nan, Tianxiang; Quintela, Camilo X.; Irwin, Julian; Gurung, Gautam; Shao, Ding-Fu; Gibbons, Jonathan D.; Campbell, Neil G.; Song, Kuyngjun; Choi, Seunghel Y.; Guo, Lu; Johnson, Roger D.; Manuel, Pascal; Chopdekar, Rajesh V.; Hallsteinsen, Ingrid; Tybell, Per Thomas Martin; Ryan, Philip J.; Kim, Jinwoong Woo; Choi, Yongseong; Radaelli, Paolo G.; Ralph, Daniel C.; Tsymbal, Evgeny Yu.; Rzchowski, Mark S.; Eom, Chang Beom (Peer reviewed; Journal article, 2020)
      The interconversion of charge and spin currents via spin-Hall effect is essential for spintronics. Energy-efficient and deterministic switching of magnetization can be achieved when spin polarizations of these spin currents ...

    • Full-field implementation of a perfect eavesdropper on a quantum cryptography system 

      Gerhardt, Ilja; Liu, Qin; Lamas-linares, Antia; Skaar, Johannes; Kurtsiefer, Christian; Makarov, Vadim (Journal article; Peer reviewed, 2011)
      Quantum key distribution (QKD) allows two remote parties to grow a shared secret key. Its security is founded on the principles of quantum mechanics, but in reality it significantly relies on the physical implementation. ...

    • Inducing a direct-to-pseudodirect bandgap transition in wurtzite GaAs nanowires with uniaxial stress 

      Signorello, G.; Lörtscher, E; Khomyakov, P.A.; Karg, S.; Dasa Lakshmi Narayana, Dheeraj; Gotsmann, B.; Weman, Helge; Riel, H. (Journal article; Peer reviewed, 2014)
      Many efficient light-emitting devices and photodetectors are based on semiconductors with, respectively, a direct or indirect bandgap configuration. The less known pseudodirect bandgap configuration can be found in wurtzite ...

    • Interstitial oxygen as a source of p-type conductivity in hexagonal manganites 

      Skjærvø, Sandra Helen; Tjønneland Wefring, Espen; Nesdal, Silje K.; Gaukås, Nikolai Helth; Olsen, Gerhard Henning; Glaum, Julia; Tybell, Per Thomas Martin; Selbach, Sverre Magnus (Journal article; Peer reviewed, 2016)
      Hexagonal manganites, h-RMnO3 (R=Sc, Y, Ho–Lu), have been intensively studied for their multiferroic properties, magnetoelectric coupling, topological defects and electrically conducting domain walls. Although point defects ...

    • Record thermopower found in an IrMn-based spintronic stack 

      Tu, Sa; Ziman, Timothy; Yu, Guoqiang; Wan, Caihua; Hu, Junfeng; Wu, Hao; Wang, Hanchen; Liu, Mengchao; Liu, Chuanpu; Guo, Chenyang; Zhang, Jianyu; Cabero Z., Marco A.; Zhang, Youguang; Gao, Peng; Liu, Song; Yu, Dapeng; Han, Xiufeng; Hallsteinsen, Ingrid; Gilbert, Dustin A.; Matsuo, Mamoru; Ohnuma, Yuichi; Wölfle, Peter; Wang, Kang L.; Ansermet, Jean-Philippe; Maekawa, Sadamichi; Yu, Haiming (Peer reviewed; Journal article, 2020)
      The Seebeck effect converts thermal gradients into electricity. As an approach to power technologies in the current Internet-of-Things era, on-chip energy harvesting is highly attractive, and to be effective, demands thin ...

    • Tunable photo-responsive elastic metamaterials 

      Descrovi, Emiliano (Peer reviewed; Journal article, 2020)
      The metamaterial paradigm has allowed an unprecedented space-time control of various physical fields, including elastic and acoustic waves. Despite the wide variety of metamaterial configurations proposed so far, most of ...
