Advanced Functional Materials, EarlyView.Dynamic linkages are highly attractive in preparing single crystals of covalent organic polymers (COPs). Here, single crystals of two COPs CityU‐15 and CityU‐16 based on reversible B─N bonds are constructed using tetra(4‐pyridyl)tetrathiafulvalene and tetra(4‐pyridyl)porphine as monomers.

Hot Carrier-Assisted Intrinsic Photoresponse in Graphene [PDF]
Science 334 (6056), p. 648-652 (2011), 2011 Graphene is a new material showing high promise in optoelectronics, photonics, and energy-harvesting applications. However, the underlying physical mechanism of optoelectronic response has not been established. Here, we report on the intrinsic optoelectronic response of high-quality dual-gated monolayer and bilayer graphene p-n junction devices.

Valence-band electronic structure evolution of graphene oxide upon thermal annealing for optoelectronics [PDF]
, 2016 We report valence-band electronic structure evolution of graphene oxide (GO) upon its thermal reduction. The degree of oxygen functionalization was controlled by annealing temperature, and an electronic structure evolution was monitored using real-time ...

Imbalanced Surface Charge Induced Phase Segregation in Mixed Halide Perovskites
Advanced Functional Materials, EarlyView.The key factor determining the phase segregation in mixed halide perovskites (MHP) is the intrinsic imbalanced surface charges in the crystal lattice. MHP films with excellent crystallinity and surface morphology can suffer severe phase segregation.

Optoelectronically probing the density of nanowire surface trap states to the single state limit [PDF]
Applied Physics Letters 106, 053117 (2015), 2014 Due to the large surface-to-volume ratio, surface trap states play a dominant role in the optoelectronic properties of nanoscale devices(1-6). Understanding the surface trap states allows us to properly engineer the device surfaces for better performance. But characterization of surface trap states at nanoscale has been a formidable challenge using the
