Planckian scattering and parallel conduction channels in an iron chalcogenide superconductor
Demir kalkojenit yüksek sıcaklık süperiletkeni üzerindeki çalışma Planckian saçılma fenomenini ve paralel iletkenlik kanallarını incelemektedir. Kuantum malzemelerde temel transport mekanizmalarının anlaşılmasına katkı sağlamaktadır.
Researchers have identified two distinct electrical conduction pathways within an iron-based superconductor, FeTe1−xSex. These pathways operate in parallel, contributing to the material's overall conductivity in its normal state. One channel exhibits a broad frequency response with minimal temperature variation, while the second is narrower and characterized by a scattering rate that scales linearly with temperature, known as the Planckian limit.
This discovery offers new insights into the complex behavior of unconventional superconductors and may shed light on the underlying mechanisms responsible for superconductivity itself.
