Universal crystallization kinetics of solution-processed semiconductors

Abstract Heterogeneous crystallization kinetics critically govern the morphology and performance of solution-processed semiconductors, yet morphology control is often achieved through trial-and-error optimization. Quantitative understanding of crystallization is essential for pre...

Control of Electronic Properties of Organic–Inorganic MXenes via Surface Functionalization

Abstract Surface terminations critically affect the electronic structure of two-dimensional (2D) transition metal carbides and nitrides (MXenes), yet the synthetic exploration has been hindered by the lack of predictive factors. Here, we establish that the number of lone-pair ele...

Graphene-based Photodetector with Engineered Hot-Carrier Cooling Dynamics

Abstract Graphene has emerged as a promising material for integration into silicon photonics, owing to its ultrafast and broadband photoresponse without the need for an external bias voltage. This photoresponse relies on the photo-thermoelectric effect created by hot carriers. A...
