Block Copolymers: Emerging Building Blocks for Additive Manufacturing

Advanced Functional Materials, EarlyView.
This review addresses how block copolymer (BCP) physics and rheology have led to the widespread use of BCPs in advanced additive manufacturing techniques, with particular emphasis on the untapped potential of these nanostructured materials toward achieving multi‐scale architected materials with unique, programmable material properties.

CaIrO3 post-perovskite, a j = 1/2 quasi-one-dimensional antiferromagnet

, 2012
The 5d5 iridate CaIrO3 is isostructural with the post-perovskite phase of MgSiO3, recently shown to occur under extreme pressure in the lower Earth's mantle.

Zwitterionic Self‐Assembled Monolayer for Simultaneous Noise Suppression and Hole Extraction in High‐Performance Near‐Infrared Organic Photodetectors

Advanced Functional Materials, EarlyView.
This study presents a new hole transporting material (HTM) mechanism for self‐assembled monolayers in near‐infrared organic photodetectors. The formation of zwitterions induces a strong electric field that significantly increases the work function of HTM‐coated indium tin oxide substrates. The devices exhibit low dark current and noise, along with high

Surface Diffusion in SnTe‐PbTe Monolayer Lateral Heterostructures

Advanced Functional Materials, EarlyView.
The lateral heterostructures between 2D materials often suffer from the interdiffusion at the interfaces. Here, a surface diffusion mechanism is found to be dominating at the interfaces between semiconducting SnTe and PbTe monolayers. Atomically sharp interfaces can be achieved by suppressing this diffusion process. ABSTRACT The construction of complex

Energy transfer mechanisms in layered 2D perovskites

The Journal of Chemical Physics, 2018
Two-dimensional (2D) perovskite quantum wells are generating broad scientific interest because of their potential for use in optoelectronic devices. Recently, it has been shown that layers of 2D perovskites can be grown in which the average thicknesses of the quantum wells increase from the back to the front of the film.

A Programmable Semiconductor Containing Active Molecular Photoswitches Located in the Crystal's Volume Phase

Advanced Functional Materials, EarlyView.
A novel approach for the design of functional semiconductors is presented, which utilizes the excellent optoelectronic properties of layered hybrid perovskites and the possibility to introduce a molecular photoswitch as the organic spacer. This concept is successfully demonstrated on a coumarin‐based system with the possibility to change the bandgap ...

Ferroelastic switching in a layered-perovskite thin film

Nature Communications, 2016
Ferroelastic switching in thin films is typically restricted by constraints from the substrate or occurs around twin-like domains. Here, the authors show reversible and non-volatile ferroelastic switching avoiding substrate constraints in layered ...

Bandwidth-disorder phase diagram of half doped layered manganites

, 2006
Phase diagrams in the plane of $r_A$ (the average ionic radius, related to one-electron bandwidth $W$) and $\sigma^2$ (the ionic radius variance, measuring the quenched disorder), or ``bandwidth-disorder phase diagrams'', have been established for ...

Suppression of Photo‐Mediated Traps in Integrated Organic Photovoltaic–Photodetector Devices via N‐Type Self‐Assembly‐Driven Interfacial Engineering

Advanced Functional Materials, EarlyView.
Conventional unstable electron transport layers (ETLs) limit self‐powered organic sensors. This work resolves this by developing a n‐type self‐assembled monolayer (SAM), “3‐PAPh”. This SAM forms a chemically stable and structurally ordered interface that fundamentally suppresses defect formation.
