“…The existence of intermediate phosphorus gas produced in the reaction progress might not be involved in the overall carbide formation of Mn and Fe. In addition, the interaction of phosphorus with metallic Fe and Mn is very strong and fast, 17,18) which was not the factor decisively affecting the rate-controlling step.…”

The dephosphorization process for high phosphorus iron ores have recently been studied employing several methods. However, few researches of phosphorus removal from high phosphorus manganese ores have been carried out compared with those about the high phosphorus iron ores. As a potential approach for the removal of phosphorus contained in the composite, the formation of (Mn,Fe)-carbide by the carbothermic reduction of the oxides of manganese and iron was investigated at 1 200°C in H2 atmosphere employing thermogravimetric analysis (TGA). It was confirmed that the phosphorus did not dissolve into the manganese iron carbide, (Mn,Fe)7C3 even though it has the high reactivity with Fe and Mn. Instead, the phosphorus generated by the decomposition of Ca3(PO4)2 reacted with Fe and Mn to form (Fe,Mn)3P. According to EPMA line mapping, (Mn,Fe)-carbide and (Fe,Mn)-phosphide coexist in the reduced particle. The current results could be applied for a promising treatment of dephosphorization of high phosphorous ores due to the low solubility of phosphorus in carbide.

SnTe has recently emerged as a 3D crystalline topological insulator exhibiting band inversion at the L point where certain crystalline symmetries allow the protection of robust topological surface states. Synthesis and development of new Dirac materials by disturbing the SnTe symmetry was accomplished by substitution of a Sn vacancy by P that maintains the intrinsic band inversion at the L point but also the direct bandgap reduction upon the incorporation of spin orbit coupling. The exotic morphology of the synthesized P-doped SnTe microneedles produces signal amplification arising from the topological surface states due to the alteration of surface area to volume ratio. Moreover, the modified effective mass, lattice imperfection, and conductivity results in a large memory window ∼3.1 V for field effect transistors accompanied by a large change in current within a certain potential range.

“…Such a system releases heat during synthesis of products of high enthalpy. 30 In this system, the form of reactants may be either fluid or solid, decided by physical parameters such as temperature, melting and boiling points of the components or their eutectic products. "Contact melting" is believed to be a possible mechanism explaining the metal-phosphorus reaction.…”

Hence, a similar mechanism is expected to be executed for other metals-phosphorus reactions.…”

The last few years have witnessed a great shift in research from conventional 2D materials and TMDCs (transition metals dichalcogenides) to new single element 2D materials, apart from Graphene. Among these, black-phosphorus (or phosphorene) was mostly investigated mainly due to appropriate mobility, bandgap tunability, and an achievable low off-state current or a high on/off ratio. Density functional theory (DFT) assisted calculations suggest that the geometries of metal doped double layer black-P are transformed from two dimensions to three dimensions. In order to analyze electrical behavior of pristine black-P, the I-V curves drawn based on the Landauer − Buttiker formula. Most of these curves exhibit a non-linear behavior and show a square dependency of current on applied potential. In the case of sulfur doped black-P, charge conduction can be partially hindered, possibly due to the formation of trace P4S3 that has a ‘cage like’ structure. The selenium doped black-P crystal shows linear characteristics, due to its semi-metallic nature, as predicted by DFT simulations. Gallium and indium doped black-P crystals exhibit ohmic character and high current density (on the order of several mA/cm2) during an application of potential, indicating the metallic nature of the material.
