论文摘要
范德华（Van der Waals）支撑声子极性准颗粒具有前所未有的光限制能力，使其成为分子传感，热发射和亚波长度成像应用的理想系统，但它们需要无缺陷的结晶度和纳米结构的形式来充分展示这些能力。我们将自下而上的合成α-MOO3结构引入纳米级声子极化系统，其具有可调量的形态和与散装单晶一致的晶体质量。 α-MOO3纳米杆菌作为低损坏双曲线Fabry-Pérot纳米孔子，我们在实验上绘制了跨越远红外光谱范围的四个RESTSTRAHLEN频段的双曲线共振，包括第十阶以外的谐振模式。迄今为止，测得的质量因子是Polaritonic Van der Waals结构中最高的。我们预计自下而上的偏光式范德华纳米结构将作为红外光学和光电应用的高性能和低损坏平台。
van der Waals nanomaterials supporting phonon polariton quasiparticles possess unprecedented light confinement capabilities, making them ideal systems for molecular sensing, thermal emission, and subwavelength imaging applications, but they require defect-free crystallinity and nanostructured form factors to fully showcase these capabilities. We introduce bottom-up-synthesized α-MoO3 structures as nanoscale phonon polaritonic systems that feature tailorable morphologies and crystal qualities consistent with bulk single crystals. α-MoO3 nanoribbons serve as low-loss hyperbolic Fabry-Pérot nanoresonators, and we experimentally map hyperbolic resonances over four Reststrahlen bands spanning the far- and mid-infrared spectral range, including resonance modes beyond the tenth order. The measured quality factors are the highest from phonon polaritonic van der Waals structures to date. We anticipate that bottom-up-synthesized polaritonic van der Waals nanostructures will serve as an enabling high-performance and low-loss platform for infrared optical and optoelectronic applications.
