Some papers on the Hall effect using current reversal?
5 answers
Current-induced switching of the Hall effect has been explored in various research papers. For instance, the photonic spin Hall effect (PSHE) can be reversed by applying a small charge current, leading to low dissipation in the heterostructure. In twisted bilayer graphene (TBG), a dc electric current can flip the sign of the Hall resistance, indicating a switching of valley polarization and topology. Additionally, a theoretical model investigates the impact of Hall current on non-local semiconductors under high temperatures, showing the Hall effect induced by a collapsing magnetic field. Furthermore, a study reveals a time-reversal even linear charge Hall effect in chiral structures like twisted bilayer graphene, enabled by interfacial coupling and exhibiting giant Hall ratios under practical conditions. These papers collectively demonstrate the intriguing phenomena of current-induced Hall effect switching in various materials and structures.

A dielectric material is a non-metallic substance with high specific resistance that can store and dissipate electrical energy, functioning as a capacitor. When subjected to an electric field, a dielectric material can store charge by rearranging charged entities within it, leading to induced polarization similar to a capacitor. These materials are crucial for various applications like capacitors, semiconductor devices, Liquid Crystal Displays, and electrical transformers, driving the need for properties such as electric susceptibility, dielectric polarization, dispersion, relaxation, and tunability. Dielectric materials can vary in composition, with examples including halogen-based elastomers or polymers mixed with surfactants to enhance properties like self-healing capabilities and increased dielectric constants. Additionally, innovative dielectric materials have been developed for specific purposes, such as a particle material designed to remove phenol contamination from underground water.

The choice of area contacts significantly impacts the reverse I-V-T measurements of Ti/6H-SiC(n) Schottky diodes. Different contact sizes (1.6 × 1.6, 1.6 × 0.4, and 0.4 × 0.4 mm^2) exhibit varying behaviors. Larger and medium-sized diodes show near-ideal characteristics following thermionic emission theory, while smaller diodes display abnormal interface inhomogeneities affecting their characteristics. Additionally, the integration of Schottky barrier diodes into SiC MOSFETs can prevent bipolar degradation issues, with the reverse conduction achieved through unipolar current, enhancing long-term reliability. Moreover, the thermal sensitivity of Ni/n-6H-SiC Schottky diodes changes after thermal annealing, affecting the linearity of the V-T and α-I graphs due to the formation of a resistive inhomogeneous layer at the interface.

What is specific price of noise reduction for electric city buses?
5 answers
The specific price of noise reduction for electric city buses varies depending on factors such as bus type, operating conditions, and surrounding traffic. Research indicates that electric buses can significantly reduce noise levels, especially in quiet residential areas, with potential reductions of up to 5 dB(A). However, noise reduction benefits may diminish on heavily trafficked roads with high bus shares and other heavy traffic. Studies comparing noise levels of different bus types show that diesel buses tend to cause the highest noise levels, while electric buses are perceived as quieter, particularly during acceleration and at bus stops. Although electric buses are generally quieter, the economic benefits of noise reduction from electric buses compared to other types remain challenging to quantify accurately due to the complexities of assessing health effects and economic costs associated with bus noise.

Which planetary boundary when stabilized would cause increased stability in other boundaries?
5 answers
Stabilizing the Lagrange stability boundary in planetary systems would lead to increased stability in other boundaries. Research indicates that while Hill stability requires planet ordering to remain constant, Lagrange stability demands all planets to stay bound to the central star. In non-resonant systems, the Hill and Lagrange stability boundaries are closely aligned, but in resonant systems, they diverge significantly. Interestingly, the region of stability in resonant interactions is unexpectedly larger than predicted by the Hill stability formula, encompassing most known resonant interactions. This finding has implications for understanding planetary system dynamics and offers new insights into planet formation models by highlighting the importance of quantifying dynamical interactions near stability boundaries.
