Ligand Assisted Epitaxial Growth of CsPbBr3 Microcrystal Resonators With Record ‐Low Lasing Thresholds

open access: yesAdvanced Functional Materials, EarlyView.
Solution‐based ligand‐assisted epitaxial growth (LAEG) yields high‐quality CsPbBr3 microcrystals on different substrates with superior morphology, passivated surfaces, and high photoluminescence quantum yield. These robust micro‐resonators achieve record‐low room‐temperature lasing thresholds of 7.2 kW·cm−2 and maintain operational stability up to 90 ...

Health effects of ionizing and non-ionizing radiation

open access: yes, 2011
This diploma thesis deals with electromagnetic radiation in its frequency spectrum. It also divides radiation into ionizing and non-ionizing. The principle of its effects and possible health problems from radiation exposure are also described.

Lone‐Pair‐Induced Lattice Distortion in Lead‐Free Hybrid Perovskites for High‐Performance Nanogenerators

open access: yesAdvanced Functional Materials, EarlyView.
A lead‐free tin‐based hybrid perovskite is designed in which stereochemically active lone‐pair electrons on tin distort the crystal lattice and break its symmetry. Blended into a flexible polymer, the material converts pressure into electricity at milliwatt‐scale power density and continues working far below freezing, powering a commercial wristwatch ...

Reaction‐Time pH Stabilization by Poly(acrylic acid) with Ethanol‐Mediated Growth Control for Efficient Hydrothermal Sb2(S,Se)3 Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
Poly(acrylic acid) acts as a reaction‐time pH buffer during hydrothermal Sb2(S,Se)3 growth through its COOH/COO‐ equilibrium. When combined with ethanol‐regulated growth, this buffering strategy reduces Sb‐O related surface disorder, improves local electronic uniformity and carrier collection, and increases the champion solar‐cell efficiency to 10.25%,

Role of Structural Disorder on Phonon Transport and Thermal Conductivity in Li6PS5Br

open access: yesAdvanced Functional Materials, EarlyView.
Solid electrolytes are fast ion and slow heat conductors. Although both transport properties are governed by lattice dynamics and atomic structure, their interplay remains poorly understood. Here, we study this interrelation in anion‐ordered and disordered Li6PS5Br.
