Electrical transport in noncentrosymmetric materials departs from the well-established phenomenological Ohm's law. Instead of a linear relation between current and electric field, nonlinear conductivity emerges along specific crystallographic directions. This is fundamentally related to lack spatial inversion symmetry. However, experimental implications an symmetry operation on remain be explored. Here, we report large, chiral tellurium. By measuring samples with opposite handedness,...
Wireless radiofrequency rectifiers have the potential to power billions of "Internet Things" (IoT) devices currently in use by effectively harnessing ambient electromagnetic radiation. However, current technology relies on implementation based Schottky diodes, which exhibit limited capabilities for high-frequency and low-power applications. Consequently, they require an antenna capture incoming signal amplify input power, thereby limiting possibility miniaturizing millimeter scale. Here,...
Nonlinear magnetoconductivity (NLMC) is a nonreciprocal transport response arising in non-centrosymmetric materials. However, this ordinary NLMC signal vanishes at zero magnetic field, limiting its potential for applications. Here, the observation of an anomalous controlled by internal order parameters such as magnetization or Néel vectors reported. This achieved breaking both inversion and time-reversal symmetry artificial van der Waals heterostructures based on CrSBr insulating hBN. The...
Here we show that by adjusting the concentration of tetrabutyl ammonium and phosphonium salts in water (≈1.5-2.0 m), hydrophobic solvation triggers formation a unique, highly incompressible supramolecular liquid, with dynamic structure similar to clathrates, involving essentially all H2 O molecules solvent. Despite increasing local order, thermal diffusivity, compressibility these liquids is strongly decreased respect bulk due slower relaxation dynamics. The results presented this paper open...
The emergence of symmetry-breaking orders such as ferromagnetism and the weak interlayer bonding in van der Waals materials offers a unique platform to engineer novel heterostructures tune transport properties like thermal conductivity. Here, we report experimental theoretical study cross-plane conductivity, κ⊥, two-dimensional (2D) ferromagnet Fe3GeTe2. We observe an increase κ⊥ with thickness, indicating diffusive regime ballistic contributions. These results are supported by analyses...
Non-linear transport effects in response to external magnetic fields, i.e. electrical magnetochiral anisotropy (eMChA), have attracted much attention for their importance study quantum and spin-related phenomena. Indeed, they permitted the exploration of topological surface states charge-to-spin conversion processes low-symmetry systems. Nevertheless, despite inherent correlation between symmetry material under examination its non-linear characteristics, there is a lack experimental...
Ohm's law has been a cornerstone of electronics since its experimental discovery. This establishes that in conductive system, the voltage is directly proportional to current. Even when time-reversal symmetry disrupted, leading emergence magnetoresistance and Hall effects, linear relationship between current remains intact. However, recent experiments have demonstrated breakdown non-centrosymmetric structures. In these systems, non-linear transport effects are permitted with quadratic scaling...
