Thinnest Covering of the Euclidean Plane with Incongruent Circles

Analysis and Geometry in Metric Spaces, 2017
In 1958 L. Fejes Tóth and J. Molnar proposed a conjecture about a lower bound for the thinnest covering of the plane by circles with arbitrary radii from a given interval of the reals.

Van Der Waals Hybrid Integration of 2D Semimetals for Broadband Photodetection

Advanced Materials, EarlyView.
Advanced broadband photodetector technologies are essential for military and civilian applications. 2D semimetals, with their gapless band structures, high mobility, and topological protection, offer great promise for broadband PDs. This study reviews the latest advancements in broadband PDs utilizing heterostructures that combine 2D semimetals with ...

Programming Defects and Cavities into Colloidal Crystals Engineered With DNA

Advanced Materials, EarlyView.
Seed‐mediated crystallization is adapted for colloidal crystals to design cavities and defect architectures through chemically programmed DNA sequences and appropriate seed particle geometry. This synthetic approach combines tenets from both atomic and colloidal crystallization to deliberately control defect formation in superlattices and enables the ...

Environmental Control of Ferroelectricity in Hafnia Films

Advanced Materials, EarlyView.
A reversible transition from nonferroelectric to ferroelectric behavior is achieved in hafnia films by modulating the surrounding atmosphere. The domain relaxation dynamics exhibit high sensitivity to environmental factors, including gas composition (ambient, N2, CO2, O2) and relative humidity, highlighting the crucial role of the measurement ...
