Treatment of PEDOT:PSS films with a superacid results in remarkable improvement thermoelectric performance power factor 142 μW m<sup>−1</sup>K<sup>−2</sup>.
A central theme in condensed matter physics is to create and understand the exotic states of by incorporating magnetism into topological materials. One prime example quantum anomalous Hall (QAH) state. Recently, MnBi2Te4 has been demonstrated be an intrinsic magnetic insulator QAH effect was observed exfoliated flakes. Here, we used molecular beam epitaxy (MBE) grow films with thickness down 1 septuple layer (SL) performed thickness-dependent transport measurements. We a non-square...
Abstract Current-induced spin torques enable the electrical control of magnetization with low energy consumption. Conventional magnetic random access memory (MRAM) devices rely on spin-transfer torque (STT), this however limits MRAM applications because nanoseconds incubation delay and associated endurance issues. A potential alternative to STT is spin-orbit (SOT). However, for practical, high-speed SOT devices, it must satisfy three conditions simultaneously, i.e., field-free switching at...
We show that the hybrid magnon-photon bundle emission is possible to generate by employing a three-level <a:math xmlns:a="http://www.w3.org/1998/Math/MathML"><a:mi mathvariant="normal">Δ</a:mi></a:math>-type superconducting artificial atom. The single atom dispersively coupled with two microwave cavities, one of which simultaneously couples yttrium iron garnet (YIG) sphere via magnetic dipole interaction. Based on virtual photon exchange, indirect magnon-atom interaction established flexibly...
The ability to electrically manipulate antiferromagnetic magnons, essential for extending the operating speed of spintronic devices into terahertz regime, remains a major challenge. This is because magnetism challenging perturb using traditional methods such as magnetic fields. Recent developments in spin-orbit torques have opened possibility accessing order parameters and controlling which has not been experimentally realised yet. Here, we demonstrate electrical manipulation sub-terahertz...
A new multifunctional material α-Ag 4 P 2 S 6 , which combines moderate photocurrent response and second harmonic generation coefficients, can be grown as mm-sized crystals with salt flux AgBr.
Interleaving magnetophotonic garnet layers with of a structurally chiral material (SCM) leads to one-dimensional helicoidal crystal, the interaction whose overall period and SCM intra-Brillouin-zone photonic band gaps which depend on structural handedness gap widths are magnetically controllable. Even as grows very large, one remains unaffected it is due period. Also, can be decreased by turning up magnitude externally impressed dc magnetic field.
A new compound Cu4TiTe4 in the Cu-Ti-Te ternary system is prepared using high-temperature solid-state synthesis and characterized by single-crystal X-ray diffraction energy-dispersive spectroscopy.

The nickel chalcogenide family contains multiple phases, each with varying properties that can be applied to an expansive range of industrially relevant processes. Specifically, pyrite-type NiS2 and NiSe2 have been used as electrocatalysts for oxygen or hydrogen evolution reactions. These pyrites also in batteries solar cells due their optoelectronic transport properties. phase pyrite polymorphism briefly studied the literature, but there has limited work focusing on transformations within...
