Clocked dynamics in artificial spin ice
(Peer reviewed; Journal article, 2024)Artificial spin ice (ASI) are nanomagnetic metamaterials with a wide range of emergent properties. Through local interactions, the magnetization of the nanomagnets self-organize into extended magnetic domains. However, ... -
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. ... -
High-quality microresonators in the longwave infrared based on native germanium
(Peer reviewed; Journal article, 2022)The longwave infrared (LWIR) region of the spectrum spans 8 to 14 μm and enables high-performance sensing and imaging for detection, ranging, and monitoring. Chip-scale LWIR photonics has enormous potential for real-time ... -
In-plane quasi-single-domain BaTiO3 via interfacial symmetry engineering
(Peer reviewed; Journal article, 2021)The control of the in-plane domain evolution in ferroelectric thin films is not only critical to understanding ferroelectric phenomena but also to enabling functional device fabrication. However, in-plane polarized ... -
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 ... -
Polarization-driven reversible actuation in a photo-responsive polymer composite
(Peer reviewed; Journal article, 2023)Light-responsive polymers and especially amorphous azopolymers with intrinsic anisotropic and polarization-dependent deformation photo-response hold great promises for remotely controlled, tunable devices. However, dynamic ... -
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 ...
