“…28 Similar behaviour was found in a theoretical study of two-dimensional black phosphorous which has an estimated high thermal conductivity leading to low zT. 30 Conversely, some MPs have low experimental thermal conductivity but with high r limiting zT, such as Zintl phases. 31 A lower r was measured for phosphide clathrates, which have also exhibited low thermal conductivities due to rattling mechanisms of the guest atoms.…”

There still exists a crucial need for new thermoelectric materials to efficiently recover waste heat as electrical energy. Although metal phosphides are stable and can exhibit excellent electronic properties, they have traditionally been overlooked as thermoelectrics due to expectations of displaying high thermal conductivity. Based on high-throughput computational screening of the electronic properties of over 48 000 inorganic compounds, we find that several metal phosphides offer considerable promise as thermoelectric materials, with excellent potential electronic properties (e.g. due to multiple valley degeneracy). In addition to the electronic band structure, the phonon dispersion curves of various metal phosphides were computed indicating low-frequency acoustic modes that could lead to low thermal conductivity. Several metal phosphides exhibit promising thermoelectric properties. The computed electronic and thermal properties were compared to experiments to test the reliability of the calculations indicating that the predicted thermoelectric properties are semi-quantitative. As a complete experimental study of the thermoelectric properties in MPs, cubic-NiP 2 was synthesized and the low predicted lattice thermal conductivity (B1.2 W m À1 K À1 at 700 K) was confirmed. The computed Seebeck coefficient is in agreement with experiments over a range of temperatures and the phononic dispersion curve of c-NiP 2 is consistent with the experimental heat capacity. The predicted high thermoelectric performance in several metal phosphides and the low thermal conductivity measured in NiP 2 encourage further investigations of thermoelectric properties of metal phosphides.

“…As the most stable allotrope of phosphorus at ambient condition, black phosphorous is a layered material with a direct band gap of 0.3 eV for bulk [109], which, combining its excellent thermal properties, is therefore proposed to be potential candidate for thermoelectric materials [110]. Thermal conductivity measurements were reported by three different groups using confocal micro-Raman method, thermal bridge method and TDTR, respectively [73,[111][112][113].…”

Recently, there have been increasing interests in phonon thermal transport in low dimensional materials, due to the crucial importance for dissipating and managing heat in micro and nano electronic devices. Significant progresses have been achieved for one-dimensional (1D) systems both theoretically and experimentally. However, the study of heat conduction in two-dimensional (2D) systems is still in its infancy due to the limited availability of 2D materials and the technical challenges in fabricating suspended samples suitable for thermal measurements. In this review, we outline different experimental techniques and theoretical approaches for phonon thermal transport in 2D materials, discuss the problems and challenges in phonon thermal transport measurements and provide comparison between existing experimental data. Special focus will be given to the effects of the size, dimensionality, anisotropy and mode contributions in the novel 2D systems including graphene, boron nitride, MoS 2 , black phosphorous, silicene etc.

“…11 Theoretically, few-layer BP have been predicted to be a promising thermoelectric material with a high zT when under stress or doping. 12,13 More interestingly, BP is a strongly anisotropic material even in the basal plane: the thermal conductivity is much higher along the zigzag than the armchair direction, while electrical conductivity shows the opposite anisotropy. 14 Choi et al 15 demonstrated that the variable range hopping (VRH) dominates electrical transport in thin BP flakes (10-30 nm thick).…”

Black phosphorus (BP) is a layered semiconductor with a high mobility of up to $1000 cm 2 V À1 s À1 and a narrow bandgap of $0.3 eV, and shows potential applications in thermoelectrics. In stark contrast to most other layered materials, electrical and thermoelectric properties in the basal plane of BP are highly anisotropic. To elucidate the mechanism for such anisotropy, we fabricated BP nanoribbons ($100 nm thick) along the armchair and zigzag directions, and measured the transport properties. It is found that both the electrical conductivity and Seebeck coefficient increase with temperature, a behavior contradictory to that of traditional semiconductors. The three-dimensional variable range hopping model is adopted to analyze this abnormal temperature dependency of electrical conductivity and Seebeck coefficient. The hopping transport of the BP nanoribbons, attributed to high density of trap states in the samples, provides a fundamental understanding of the anisotropic BP for potential thermoelectric applications.
