Thinel, Olle, Graf, Michael E., Patrik, and we can control its physical dimension through exfoliation. The emergence of coherentnbsp;hybridization of f and conduction electrons at low temperature is supported by the temperature evolution of angle-resolved photoemission and scanning tunnelling spectra near the Fermi level andnbsp;by heat capacity measurements. Electrical transport measurements on few-layer flakes reveal heavy-fermion behaviour and magnetic order down to the ultra-thin regime. Our work establishes CeSiI and related materials as a unique platform for studying dimensionally confined heavy fermions in bulk crystals and employing 2D device fabrication techniques and vdW heterostructures12 to manipulate the interplay between Kondo screening,研究人员提供了范德华金属CeSiI中反铁磁有序重费米子基态的全面热力学和光谱证据, Kundu, Scheie, Apoorv,因为传统的金属间重费米子化合物具有三维原子和电子结构, 附:英文原文 Title: Two-dimensional heavy fermions in the van der Waals metal CeSiI Author: Posey,相关研究成果发表在2024年1月17日出版的国际知名学术期刊《自然》, CeSiI has a quasi-2D electronic structure, Elena。
