Highly Oriented Epitaxial Hexagonal Boron Nitride Multilayers on High‐Temperature‐Resistant Single‐Crystal Aluminum Nitride (0001)

Advanced Science, EarlyView.
High‐temperature‐resistant single crystals of aluminum nitride works best for multilayer hexagonal boron nitride (hBN) epitaxy and annealing on large‐area dielectric wafers, promising for large‐scale integration and device applications of hBN. Abstract The epitaxy of high‐quality hexagonal boron nitride (hBN) multilayers on dielectric wafers is ...

Scattering‐Enhanced Light Extraction for Radiative Thermal Load Mitigation in Fluorescent Films

Advanced Science, EarlyView.
Scattering‐enhanced light extraction overcomes total internal reflection limitations in fluorescent films, expanding the sub‐ambient cooling color range from 26.7% to 64.9% in CIE 1931 space. Optimal TiO2 nanoparticle doping (0.5 wt.%) achieves 85.9% light extraction efficiency and 89.5% visible reflectance.

High‐Temperature Single‐Photon Emission From Covalently Functionalized van der Waals Heterostructures

Advanced Science, EarlyView.
Covalent diazonium functionalization of graphite‐WSe2 heterostructures produces high‐purity single‐photon emission from WSe2 at T = 90 K, far above the typical T = 10 K limit. The chemical modification reshapes graphite's electronic structure and couples to WSe2 midgap states, stabilizing quantum emitters at elevated temperatures and opening pathways ...
