From Symmetry to Stability: Structural and Electronic Transformation in Cs2_2KInI6_6

This study employs a synergistic approach combining genetic algorithms, machine-learned potentials, and first-principles calculations to reveal that the lead-free double perovskite Cs2_2KInI6_6 lacks a stable cubic phase, instead identifying lower-symmetry structures that trade structural stability for widened, indirect band gaps.

Controlled Chemical Signaling between Enzymatic Nanomotors

This study demonstrates controlled chemical signaling between two distinct populations of enzymatic nanomotors, where a glucose-responsive swarm generates a hydrogen peroxide gradient that guides the migration of a secondary catalase-powered swarm, thereby achieving programmable collective behavior through non-reciprocal phoretic interactions.

Physical properties of R2_2Co6_6Al20δ_{20-\delta} (R = Gd-Tm, Y) single crystals

This study reports the synthesis and characterization of single-crystal heavy rare-earth R2_2Co6_6Al20δ_{20-\delta} (R = Gd-Tm, Y) compounds, revealing their orthorhombic structure, antiferromagnetic ordering with complex transitions, and the significant interplay between RKKY exchange and crystal electric field effects that leads to deviations from de Gennes scaling.

Barrier-channel intermixing and 2-dimensional electron gas degradation in Al-rich Al(Ga)N/AlGaN high electron mobility transistor heterostructures

This paper addresses the degradation of 2-dimensional electron gas in high-aluminum AlGaN/AlGaN heterostructures caused by high-temperature growth-induced interface intermixing, demonstrating that optimized growth schemes combined with X-ray diffraction analysis can restore sharp interfaces and achieve high-quality 2DEGs with sheet resistivities around 2,500 Ω/\Omega/\Box.
