“…Here, we hypothesize that three phases actually play a role in the superconducting phase diagram, namely, black-P, R3m, and sc, and that the bifurcation in T C seen by experiments is due to the coexistence the ground-state low-T C A7-P and high-T C metastable black-P phases, which both collapse to sc at P ≈ 20 GPa. Our hypothesis perfectly accounts for the existing literature results of Kawamura et al [30], in which the pressure cell was initially loaded with black-P and pressure was subsequently increased, either keeping the system at low temperature (Kawamura, path B in Fig. 1) or following a room-temperature path (paths A and C).…”

“…We propose that the coexistence of two distinct superconducting phases of phosphorus in the 10-30 GPa pressure window successfully accounts for the the "anomalous" T C vs P trend first observed by Kawamura and co-workers [30]. Furthermore, we identified theoretically two other pressure regions in which superconducting T C anomalies could be observed depending on the experimental conditions.…”

“…1 compares the previous experimental results (gray symbols and lines) with our experiments (black symbols and lines). The first accurate resistivity measurements on P under compression date back to 1985 and were performed by Kawamura et al [30]. The authors reported an anomalous behavior in the superconducting transition temperatures up to pressures of 30 GPa: the value of T C was found to strongly depend on the P − T path followed in experiment.…”

“…Summary of all the critical temperatures observed experimentally [30][31][32] (top panels) and calculated theoretically in this work (bottom panels). In the experimental panels the dashed and full lines are guidelines to the eye and are used to distinguish the trend that we interpret as due to metastable black-P (dashed) from the energetically stable sequence of transformations (see text).…”

Pressure-induced superconductivity and structural phase transitions in phosphorus (P) are studied by resistivity measurements under pressures up to 170 GPa and by fully ab initio crystal structure exploration and superconductivity calculations up to 350 GPa. Two distinct superconducting transition temperature (T C ) vs pressure (P ) trends at low pressure have been reported more than 30 years ago, and we are able to devise a consistent explanation founded on thermodynamically metastable phases of black phosphorus. Our experimental and theoretical results form a single, consistent picture which not only provides a clear understanding of elemental P under pressure but also sheds light on the longstanding and unsolved anomalous superconductivity trends. Moreover, at higher pressures we predict a similar scenario of multiple metastable structures which coexist beyond their thermodynamical stability range. We observe that all the metastable structures systematically exhibit larger transition temperatures than the ground-state structures, indicating that the exploration of metastable phases represents a promising route to design materials with improved superconducting properties.

“…First we notice that in case of the substances P and As, superconductivity is induced only when the crystal structure is changed to the high-symmetry (simple cubic) phase by high pressure [15][16][17]. In the ambient pressure the Peierls instability makes the crystal structure low-symmetry phase, as clarified in precise ab-initio calculations [18].…”

Elemental phosphorus in its various allotropes has received tremendous research attention recently due to its intriguing electronic and structural properties. Notably, the application of nanostructured materials to overcome the inherent flaws in bulk materials is promising. However, many challenges need to be addressed before its widespread implementation. Thus, a specific tenet to design novel and robust nanomaterials is a decisive factor in the desired outcome, and the most daunting task before realizing this is solving the Schrödinger equation. First principle density functional theory (DFT) calculations have emerged as an insightful and accurate design tool to investigate the structural, electronic, and possible synthesis scenarios of yet undiscovered materials at atomic levels. In this review, the basic principles and the importance of DFT are discussed, followed by a summary of recent advances in the first principle study of elemental phosphorus‐based nanomaterials. Elemental phosphorus‐based nanomaterials and their allotropes have attracted growing interest in the renewable energy community due to their modulable product selectivity. However, the understanding of the physical phenomena of allotropic modification is still lacking. Therefore, the aim is to motivate experimental researchers to conduct DFT studies and experiments to comprehend relevant engineered nanomaterials better. Finally, the challenges and potential future research directions for further theoretical and computational development of phosphorus‐based nanomaterials are outlined.
