Unveiling the hybridization between the Cr-impurity-mediated flat band and the Rashba-split state of the α-Au/Si(111) surface

Abstract

Adsorption of foreign atoms onto the 2D materials can either lead to the ordinary electron doping or to the emergency of the new electronic effects including topology, superconductivity, quantum anomalous...

Rashba effect: a chemical physicist's approach

“…13,43,44 Current research continues to explore the development of surface modifications. [45][46][47][48][49][50] However, it also delves into GSS induced in novel 2D layered materials, including transition-metal dichalcogenides (TMDs), [51][52][53][54][55][56][57] MXenes, [58][59][60][61][62][63] and a variety of other sheets. [64][65][66][67][68][69][70][71][72] To facilitate the ongoing efforts, it is crucial to develop more robust strategies for enhancing spin splitting.…”

A 2D heavy fermion CePb3 kagome material on silicon: emergence of unique spin polarized states for spintronics

“…There are examples of rare-earth/noble metal monolayer compounds, such as GdAu 2 , HoAu 2 , and YbAu 2 grown on Au(111), demonstrating a high temperature ferromagnetic transition, 18 or incorporation of Cr magnetic impurity into the Au monolayer on Si(111) enhancing the electronic correlations. 32 In the present paper we report on the successful synthesis and comprehensive experimental and theoretical study of the novel 2D compound composed of Ce and Pb atoms on silicon. We show that the merging of heavy-fermion magnetic and "superconducting" elements together on the semiconductor surface at the ultimate two-dimensional limit induces intriguing spin-polarized states, which may be employed for spintronic applications.…”
