Despite the large number of III–V semiconductor studies reported every year at bulk level, the III–V material characterization at nanoscale is still required to evaluate their potential industrial applications in nanoscale electronic devices, optoelectronic devices, chemical, biosensors, etc. In this work, the non-destructive evaluation-based ultrasonic theoretical approach for the material characterization of nanostructured IIIrd group phosphides, namely indium phosphide (InP), aluminum phosphide (AlP), gallium phosphide (GaP), and boron phosphide (BP) with wurtzite crystal phase, has been reported. The second- and third-order elastic constants (SOECs and TOECs) for IIIrd group phosphides have estimated using the Lennard–Jones potential. The mechanical properties and the ultrasonic investigation of the IIIrd group phosphides materials, e.g., ultrasonic velocities, Grüneisen parameters, acoustic coupling constants, and ultrasonic attenuation, have been performed using the estimated values of SOECs and TOECs. The present investigation indicates that the ultrasonic attenuation of IIIrd group phosphides is influenced by the wave velocities and the chosen material’s thermal conductivity. The other thermophysical parameters like the crystal energy density, the specific heat per unit volume, thermal conductivity, and the Debye temperature of these materials have also been reported at room temperature (300 K). The results indicate that BP is the most robust material and has superior elastic, mechanical, and thermal characteristics.

尽管每年都进行大量的III-V半导体研究，但仍需要进行纳米级的III-V材料表征，以评估其在纳米级电子设备，光电子设备，化学，生物传感器等方面的潜在工业应用。的工作，基于无损评估的超声理论方法，用于表征具有纤锌矿晶体的磷化铟（InP），磷化铝（AlP），磷化镓（GaP）和磷化硼（BP）的纳米结构IIIrd磷化物的材料阶段，已有报道。第三类磷化物的二阶和三阶弹性常数（SOEC和TOEC）已使用Lennard-Jones势进行了估算。第三族磷化物材料的机械性能和超声研究，例如 超声速度，Grüneisen参数，声耦合常数和超声衰减已使用SOEC和TOEC的估计值执行。本研究表明，IIIrd族磷化物的超声衰减受波速和所选材料的热导率的影响。还已经报道了这些材料的其他热物理参数，例如晶体能量密度，每单位体积的比热，热导率和德拜温度，在室温（300 K）下。结果表明，BP是最坚固的材料，并具有出色的弹性，机械和热学特性。本研究表明，IIIrd族磷化物的超声衰减受波速和所选材料的热导率的影响。还已经报道了这些材料的其他热物理参数，例如晶体能量密度，每单位体积的比热，热导率和德拜温度，在室温（300 K）下。结果表明，BP是最坚固的材料，并具有出色的弹性，机械和热学特性。本研究表明，IIIrd族磷化物的超声衰减受波速和所选材料的热导率的影响。还已经报道了这些材料的其他热物理参数，例如晶体能量密度，每单位体积的比热，热导率和德拜温度，在室温（300 K）下。结果表明，BP是最坚固的材料，并具有出色的弹性，机械和热学特性。这些材料的德拜温度也已在室温（300 K）下报道。结果表明，BP是最坚固的材料，并具有出色的弹性，机械和热学特性。这些材料的德拜温度也已在室温（300 K）下报道。结果表明，BP是最坚固的材料，并具有出色的弹性，机械和热学特性。
