Resonant Interlayer Coupling in NbSe2‐Graphite Epitaxial Moiré Superlattices

Advanced Materials, EarlyView.
Combining angle‐resolved photoemission spectroscopy and density functional theory derived calculations, this work reveals strong interlayer coupling and moiré replicas of the graphite π states in molecular‐beam epitaxy grown van der Waals heterostructures of monolayer‐NbSe2/graphite, with implications for its collective phases that form.

Halide Perovskite–Chalcohalide Nanocrystal Heterostructures as a Platform for the Synthesis and Investigation of the CsPbCl3–CsPbI3 Epitaxial Interface

Advanced Materials, EarlyView.
In this work, perovskite–chalcohalide CsPbCl3–Pb4S3Cl2 heterostructures are exploited to study the Cl→I exchange reaction and to isolate new types of intermediate structures, in particular emissive CsPbI3–CsPbCl3–Pb4S3Cl2 heterostructures, with partial I‐alloying of the CsPbCl3 domain and at the perovskite–chalcohalide interface, having a 5.6% lattice ...

Disorder Scattering Induced Large Room Temperature Nonlinear Anomalous Hall Effect in a Semiconductor CdGeAs2

Advanced Materials, EarlyView.
Bulk CdGeAs2, a well‐known nonlinear optical semiconductor, exhibits an exceptionally large room‐temperature nonlinear Hall effect (NLHE), achieving a record‐high nonlinear Hall responsivity of 2.2 × 10−3 m/V. This pronounced NLHE enables broadband frequency mixing up to the megahertz regime, establishing CdGeAs2 as a promising platform for next ...

Transient stability and control of renewable generators based on Hamiltonian Surface Shaping and Power Flow Control: Part I-theory

2010 IEEE International Conference on Control Applications, 2010
The swing equations for renewable generators connected to the grid are developed and a wind turbine is used as an example. The swing equations for the renewable generators are formulated as a natural Hamiltonian system with externally applied non-conservative forces.

Investigating the Structural Factors Influencing the Magnetic Interaction between Individual Copper Spins in the CuCu4 Metallacrown Complex, from Its Bulk Form to Its Adsorption on Au(111)

Advanced Materials Interfaces, EarlyView.
The Cu(II)[12‐MCCu(II)N(Shi)‐4] metallacrown complex (CuCu4) is studied to examine how geometric transformations affect magnetic coupling between copper spins by using ultraviolet photoemission spectroscopy and DFT calculations for the bulk phase and CuCu4 adsorbed on Au(111). While adsorption minimally affects tDOS, exchange coupling constants between
