Controlling spin current polarization through non-collinear antiferromagnetism
(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
(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
(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
(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
(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
(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 ...
