Article Synopsis
- The study investigates the optical conductivity and magnetotransport properties of top-gated devices made from the topological insulator BiSe, focusing on how different carrier types within the material interact.
- Findings reveal that the topologically protected surfaces are somewhat shielded from gate control due to trivial band-bending states but still show significant mobility changes based on external gate bias.
- The research highlights that the optical conductivity is largely influenced by the topological surface states and is particularly affected by scattering from trivial states, suggesting potential uses in future plasmonic device designs.
A Heat Flux Sensor (HFS) facilitates the visualization of heat flow, unlike a temperature sensor, and is anticipated to be a key technology in managing waste heat. Recently, an HFS utilizing the Anomalous Nernst Effect (ANE) has been proposed garnering significant interest in enhancing the transverse thermopower. However, ideal materials for HFS not only require a large transverse thermopower but also meet several criteria including low thermal conductivity and a bipolar nature of the transverse thermopower, especially a negative transverse thermopower.
