论文摘要
声波作为声音科学，是物理学的既定领域。与光相比，工程师从光场适应了操纵声波以与癌细胞作斗争的工具。在这里，我们提出了一个热量驱动的纳米机械概念，用于同时发射两个声子，即将热量转化为声波输出。我们的理论工作阐明了可用于未来超声设备的纳米级组件或系统。
Acoustic waves, as science of sound, is an established field in physics. In analogy with light, engineers adapt tools from optic fields for manipulating sound waves to fight with cancer cells. Here we present a heat-gradient driven nanomachine concept for simultaneous emission of two phonons, i.e. a convertion of heat into a sonic wave output. Our theoretical work sheds light on nanoscale components or systems that could be used for future ultrasound devices.
