Abstract

This work presented a cost-effective and simple route for the fabrication of high-quality and large lateral-size black phosphorus nanoparticles/nanosheets by liquid-phase exfoliation.

Sonochemically synthesized black phosphorus nanoparticles: a promising candidate for piezocatalytic antibacterial activity with enhanced dielectric properties

“…This reduction served as clear evidence of the decrease in thickness and lateral size of the nanoparticle. 44 The thickness reduction effect induced by the sonochemical method was likely to lead to an increased bandgap, possibly attributed to the decrease in grain crystalline size, subsequently causing alterations in atomic distances. 45 Apart from these three bands, the signal at approximately 398 cm −1 for TABP and 403 cm −1 for SCBP might be attributed to the P–O species, indicating the partial oxidation phenomenon.…”

“…Sarwar et al had reported a bandgap of 1.96 eV for BP nanoparticles/nanosheets synthesized using the liquid phase exfoliation method. 44 In the study by Pan et al , the energy bandgap of the BP quantum dots was determined to be 2.68 eV. 50 Chen et al explored the bandgap of BPQDs, determining it to be 2.25 eV.…”

Recent advancements have significantly improved growth techniques for producing large-scale 2D materials 96 , 97 . However, the assembly of different materials limits their CMOS compatibility.…”

Noncovalent Functionalization of Black Phosphorus: Free Energy Simulations vs Adsorption Experiments

“…Improving exfoliation and surface protection of black phosphorus while maintaining its stability and properties is a crucial precondition for its wide application in electronics and optoelectronics. , Black phosphorus has very appealing properties such as thickness-dependent, direct band gap ranging from ∼0.3 eV in the bulk to ∼2 eV in the monolayer (i.e., phosphorene), − room temperature carrier mobilities up to ∼200–1000 cm 2 V –1 s –1 , − and current on/off ratios of ∼10 4 –10 5 . , These favorable electronic properties make BP a desirable candidate for high-performance electronic and optoelectronic device applications. However, exposure of BP flakes to ambient in the long term (days) has shown etching processes and degradation, and single- and few-layer BP may deteriorate within hours. , Simply put, the high oxophilicity of phosphorus leads to the gradual oxidation of the BP surface …”
