Electronic Coupling Between Perovskite Nanocrystal and Fullerene Modulates Hot Carrier Capture
1 Introduction In semiconductor optoelectronics applications, a significant portion of absorbed photon energy is lost as heat before charge carriers can be collected, fundamentally limiting device efficiencies.[1, 2] Hot carrier (HC) optoelectronics offers a paradigm-shifting approach to overcoming these limitations.[3-5] By harnessing charge carriers before they cool to lattice temperatures, HC-based devices have the potential to revolutionize a wide spectrum of applications.

The Role of the Organic Cation in Developing Efficient Green Perovskite LEDs Based on Quasi‐2D Perovskite Heterostructures
1 Introduction Metal halide perovskite light-emitting diodes (PeLEDs) are set to be a highly exciting new technology due to their highly efficient[1] tunable narrow emission spectra,[2] and their compatibility with low-cost fabrication processes.[3] Since initial reports,[4, 5] vast increases in efficiency, stability,[6, 7] and a broad range of feasible colors have been reported.[8-11] Considerable research interest has been directed to optimizing the formation of the perovskite emitter, to...

Tuning electronic and optical properties of graphane/silicane and fhBN/silicane nanosheets via interfacial dihydrogen bonding and electrical field control - Journal of Materials Chemistry C (RSC Publishing)
In this work, using density functional theory (DFT) computations with van der Waals (vdW) corrections, the effects of dihydrogen bonding on the stability, electronic and optical properties of graphane/silicane heterobilayer and fully hydrogenated hexagonal boron nitride (fhBN)/silicane heterobilayer are investigated.
Tunable electronic structure and enhanced optical properties in quasi-metallic hydrogenated/fluorinated SiC heterobilayer
Graphene-like silicon carbide (SiC) has emerged as a rapidly rising star on the horizon of two-dimensional (2D) layered materials. In this work, we execute a systematic theoretical investigation of the atomic and electronic structure of fully hydrogenated/fluorinated SiC (H/F-SiC) heterobilayer, which process a quasi-metallic character in its most stable stacking pattern, to predict its electronic and optical properties.
The electronic and optical properties of silicene/g-ZnS heterobilayer: a theoretical study
Two-dimensional (2D) nanomaterials have rapidly become the superstars in the fields of nanoelectronics, materials science, and energy storage because of their unusual properties, originating from the quantum size effects. Here we present a systematically theoretical investigation of the electronic and optical properties of silicene/g-ZnS heterobilayer, by means of dispersion-corrected density functional theory (DFT-D) computations.
