Abstract Black phosphorus is a two-dimensional material of great interest, in part because its high carrier mobility and thickness dependent direct bandgap. However, instability under ambient conditions limits deposition options for device fabrication. Here we show black ink that can be reliably inkjet printed, enabling scalable development optoelectronic photonic devices. Our binder-free suppresses coffee ring formation through induced recirculating Marangoni flow, supports excellent...

Being capable of sensing broadband infrared (IR) light is vitally important for wide-ranging applications from fundamental science to industrial purposes. Two-dimensional (2D) topological semimetals are being extensively explored IR detection due their gapless electronic structure and the linear energy dispersion relation. However, low charge separation efficiency, high noise level, on-chip integration difficulty these significantly hinder further technological applications. Here, we...
Two-dimensional (2D) black phosphorus (BP) shows thickness dependent direct energy band-gaps in association with strong light-matter interaction and broadband optical response, rendering it promising optoelectronic advantages particularly at the telecommunication band. However, intrinsic BP suffers from irreversible oxidization, restricting its competences toward real device applications. As one potential of 2D materials, all-optical signal processing sensitively depends on strength...
