Electrically Tunable Momentum Space Polarization Singularities in Liquid Crystal Microcavities

Advanced Science, EarlyView.
Using a highly birefringent material embedded in a liquid crystal microcavity, the Rashba‐Dresselhaus resonance is obtained. In this regime, polarization singularities, known as C‐points, are observed in momentum space. The positions of these singularities can be modified by applying an external voltage to the sample.

A Soft‐Soft Contact Triboelectric Nanogenerator with a Ternary Four‐Phase Structure for Self‐Powered High‐Efficiency Dust Removal on Mars

Advanced Science, EarlyView.
The frequent dust storms and charged dust particles on Mars pose significant challenges to the power generation efficiency and service life of solar panels during exploration missions. This paper proposes a novel wind‐driven ternary four‐phase soft‐soft contact triboelectric nanogenerator (FPS‐TENG) for dust removal.

Self‐Powered UV Dual‐Band Photodetector Based on Cs3BiCl6/GaN Heterojunction for Logical Operation and Encrypted Photo‐Communication

Advanced Science, EarlyView.
Utilizing the special dual‐band absorption characteristics of Cs3BiCl6 and its strong surface‐charge recombination behavior, a self‐powered UV dual‐band photodetector based on Cs3BiCl6/GaN heterojunction is developed. As a result, the photodetector exhibits excellent specific detectivity of 1.23 × 1012 Jones and ultrafast response speed of τr/τf = 28 ...

Effect of Inhomogeneous Temperature in Chip‐Scale Infrared Thermal Sources: A Revisited Blackbody Radiation Formula with Experimental Validation

Advanced Electronic Materials, EarlyView.
Revisited Black‐body radiation formula accounting for nonuniform temperature is proposed for calibration of planar thermal light sources. Calibration of optical power is based on measurement of the highest and lowest temperatures. Abstract Miniature and low‐cost light sources are highly desirable for numerous optical microsystems.
