| Abstract Scope |
Layered black phosphorus (BP) continues to attract significant interest in optoelectronic devices like photodetectors and lasers due to its layer-dependent and direct bandgap. However, large-scale optoelectronic device fabrication using exfoliated BP is challenging due to the cost of single-crystal raw materials and to BP oxidation from ambient exposure. To address these concerns, we present a viscous (~12cP), highly concentrated BP ink exfoliated in anhydrous and oxygen-free solvents. We can aerosol jet print with this BP ink, thereby enabling conformal and high-resolution BP prints. Height measurements by stylus profilometry indicate that ~100 nm of material is deposited per each print pass. However, multiple passes are required for uniform coverage. We validate the vibrational and optical properties of the BP prints by Raman and photoluminescence (PL) emission spectroscopy. The prints possess the expected 3 Raman modes and PL emission at ~1550 nm, a wavelength of considerable relevance for optical communications. |
