What is Surface Modification of Black Phosphorus with Group 13 Lewis Acids for Ambient Protection and Electronic Tuning about?
Herein we introduce af acile,s olution-phase protocol to modify the Lewis basic surface of few-layer black phosphorus (bP) and demonstrate its effectiveness at providing ambient stability and tuning of electronic properties.Commercially available group 13 Lewis acids that range in electrophilicity,steric bulk, and Pearson hard/soft-ness are evaluated. The nature of the interaction between the Lewis acids and the bP lattice is investigated using arange of microscopic (optical, atomic force,s canning electron) and spectroscopic (energy dispersive,X -ray photoelectron) methods.A la nd Ga halides are most effective at preventing ambient degradation of bP (> 84 hf or AlBr 3 ), and the resulting field-effect transistors show excellent IV characteristics,p hotocurrent, and current stability,a nd are significantly p-doped. This protocol, chemically matched to bP and compatible with device fabrication, opens ap ath for deterministic and persistent tuning of the electronic properties in bP.
