Abstract
Polycrystalline black phosphorus has a hydrostatic piezoresistive coefficient πH=3.04×10−10 cm2/dyn independent of pressure and decreasing by 28% between 0° and 100°C, and a highly stress-sensitive uniaxial piezoresistive stress coefficient πl>3×10−9cm2/dyn under appropriate conditions. The thermoelectric power is in the range 330 to 413 μV/deg, and Young's modulus=6.89×1010±15% dyn/cm2, linear to at least 4×106 dyn/cm2 tension. The ultimate tensile strength is 3.4×107 dyn/cm2 and the ultimate compressive strength is 3.5×108 dyn/cm2. These properties of black phosphorus make it potentially useful for strain and hydrostatic gauges, and other transducer use. The advantages and disadvantages relative to other materials are discussed briefly.
