英文摘要	van der Waals (vdW) materials have always been a fertile ground for exploring pressure-tuned dimensional crossover and novel physical properties, such as superconductivity. Nevertheless, few of the dimensional crossovers with an accompanying superconductivity occur at a low pressure close to environmental conditions. Here, we predicted a novel C2/m structure of LiP15 which can be achieved by compressing the experimentally synthesized P (1) over bar structure above 2 GPa. Under compression, LiP15 goes through a one- to quasi-two-dimensional crossover and an accompanying semiconducting to superconducting electronic transition. The C2/m structure is a superconductor with an increasing transition temperature under pressure that reaches up to 14.2 K at 15 GPa. In addition, we found that the phosphorus allotrope obtained by removing lithium atoms in the C2/m structure is dynamically stable, and its energy is almost equivalent to that of black phosphorus at ambient pressure. These findings not only pave a new way to design a new vdW material by means of pressure-induced dimensional crossover, but also provide a possibility for searching a new vdW superconductor in similar systems.
