Atomically Resolved Electron Reflectivity at a Metal/Semiconductor Interface
Advanced Science, EarlyView.An atomically flat interface is achieved in the incoherent Al/Ge heterostructure using molecular beam epitaxy (MBE). Scanning tunneling microscopy (STM) reveals a laterally periodic modulation of electron reflectivity with atomic resolution at the commensurate Al/Ge interfacial lattice, originating from the local electronic states.

d‐Wave Fermi Surface Instability in the Nematic Phase of Two Monolayer FeSe/SrTiO3
Advanced Science, EarlyView.Angle‐resolved photoemission spectroscopy reveals a d‐wave nematic order in two‐monolayer FeSe/SrTiO3, showing degenerate dxz/dyz bands at Γ but a pronounced splitting at M. This momentum‐dependent anisotropy identifies the nematicity as a d‐wave Fermi surface (Pomeranchuk) instability, highlighting 2D FeSe as a model platform to explore the interplay ...

Hidden Charge‐Order in the Mixed‐Valent K0.75Li2Cr6O12 High‐Pressure Oxide
Advanced Science, EarlyView.K0.75Li2Cr6O12 is one of the few mixed valent chromium oxides. It shows a single angle spiral magnetic structure with a k = [1/3 1/3 ¼] propagation vector. Density functional theory reveals a hidden charge order that is necessary to stabilize the antiferromagnetic (AFM) ground state.

Origins of Graphite Resistivity: Decoupling Stacking Fault and Rotational Misorientation
Advanced Science, EarlyView.Interfacial dislocations critically influence interlayer transport in van der Waals (vdW) materials, yet quantifying their individual contributions remains challenging. We measure graphite's c‐axis resistivity and develop a decoupling strategy, revealing a resistivity ratio of ∼4507:74:1 for rotational misorientations, stacking faults, and AB stacking,

Semiconducting THO‐C3N Monolayers for Ultrahigh Anisotropic Carrier Mobility
Advanced Science, EarlyView.A precise site‐specific N‐doping strategy that drives a secondary electronic transition in net W is proposed, enabling the electronic properties transition from metal to Dirac semimetal and ultimately to semiconductor. The obtained THO‐C3N‐2 and THO‐C3N‐3 semiconductors exhibit high carrier mobilities and pronounced mobility anisotropy, with THO‐C3N‐2 ...

Lactone-Terminated Self-Assembled Monolayers for Mimicking Nanoscale Polyester Surfaces
ChemistryTwo series of lactone-terminated alkanethiol adsorbates with five- and six-membered lactone groups, γ-COCnSH and δ-COCnSH (n = 11, 12), were synthesized and employed to create nanoscale self-assembled monolayers (SAMs) on gold substrates to mimic the ...
